Richard, it seems you're shooting just a little off the mark lately. 
It's quite unusual for you to be inaccurate, and I've known you for a 
long time. If you have any personal issue with me, accept my apologies 
and best regards, but whatever it may be, don't let any feelings throw 
off your reading and writing accuracy and honesty. Facts, statements, 
and chronology are all public for reference. Sticking a little closer to 
them would be appreciated.

So now we may be triple-conflated. different general LC 9 ENGINE 
performance optimization issues is a completely different topic that 
doesn't belong in this thread and has ONLY been introduced here courtesy 
of yourself, Mr. Richard Gaskin. Nothing to do with me.

That (not of this thread, again cross-threaded by yourself, Richard) was 
something I've promoted publicly since Jan 2017, and discussed with LC 
prior. And (I explain here ONLY because you force me, to avoid needless 
confusion to others, since you've now accused me of injecting it 
globally) in Sep 2018 I filed Bug 21561 "Slow LC 9 LCS Performance in 
Multiple Areas and Real Applications" to demo irrefutable effects in 
multiple areas of engine code BECAUSE at the time discussions of the 
optimization effort underway were focusing mainly on arrays. I mentioned 
it again in another thread BECAUSE in discussing 6/9 factoring OTHERS 
had already mentioned performance. These are all published, and we can 
quote and link if you wish, but not on this thread, please. Your recent 
comments about that bug report were off too, but I don't want to follow 
you on this cross-thread stuff.

I can't see any possible need to bring that topic here into this thread, 
and I'm not sure why you saw fit to do so, but again, that was you, 
RICHARD GASKIN, injecting it here, and not myself. Here in this thread I 
briefly mentioned (quote) "plus improved performance as a bonus" i.e. a 
possible (not guaranteed) extra INCENTIVE for fixing one of these AV 
problems, what you call the "Defender issue."

That "Defender issue" - in other words, my other Bug 21604 "Script 
Editor for LC 901 Unusable on Windows i3/i5" - and the other AV flagging 
issue (whether by Defender or any other AV) are both what OTHERS 
introduced to this thread when discussing AV, including yourself. Which 
is fine by me (both AV) but let's keep the chronology and facts 
straight: note that ANY and all conflation (or not) on this thread 
happened before my post today. Except this conflation of yours, of 
course! :)

Again, you are straying from PUBLISHED details and chronology. In fact, 
in the very source you mentioned. On Nov 16, the Defender fix was noted. 
On Dec 12, I acknowledged that it was the case for me too, and thanked 
them for it. I don't think you can accuse me of not noticing something 
that I explicitly acknowledged, can you? And what I've emphasized today 
is a great quick fix for the symptoms? To overlook multiple statements 
of mine and suggest the opposite is going off the rails a little.

On Dec 12, I also warned about telling people to turn off Defender per 
se rather than just the affected part, which Panos then identified.

And on that date I mentioned my suspicion/prediction (since others 
reported similar symptoms on Mac, plus typing in a window shouldn't be a 
biggie) that there was more to this than Defender/AV, potentially the 
code design of SE and/or IDE.

Yes, that's where we've agreed, to that extent - that there may be a way 
to fix it/avoid it on the LC side. On Dec 12 I suggested it along my 
lines, and later the same day you suggested it along slightly different 
lines based on MS reports. I don't know whose theory will prove to be 
correct, but both possible and involving a shared component: changing 
something in LC to avoid this issue permanently.

 > If the performance issues you're seeing on your Mac
 > Any Mac-specific issues merit their own bug report as well

That's only true if your assumption or theory is correct. It hasn't been 
resolved yet. Although my bug report is titled Windows (because I 
queried others before posting report and didn't notice or receive any 
Mac reports before posting) I did receive Mac reports AFTER posting. And 
this is all noted in the same report that you referenced.

Precisely, so Richard, would you agree that me posting on this thread 
once might be just a tad relevant, it being the bug I reported? Is that 
OK? I posted (A) to remind people of the Defender areas that can be left 
on, (B) to remind people that if Macs are involved it's not ONLY a 
Defender/AV issue and can be solved on the IDE side, and (C) to note the 
conflation that you also followed me in posting again with some 
differences. All important - I've let this thread go on without my 
involvement, but wanted to post once to make sure those were emphasized.

As a result of my posting the bug report, I was informed by Mac users 
who claimed similar symptoms and finally saw it myself with my own eyes. 
Noted in the bug report. Perhaps you were not informed and didn't notice 
those. A possible projection of the "you may not have noticed" that you 
attributed to me? I wouldn't have minded that you didn't see something 
(I sure don't see everything) but it's a bit strange to be accused of 
what may be the accuser's problem.

Since Mac is less commonly affected with similar symptoms (in fact LC 
Ltd suggested a workaround, that's documented in the report) it follows 
that POSSIBLY they are of the same cause. And IF they are, it becomes 
CERTAINLY not just a Windows Defender issue, obviously. But we'll have 
to wait for the final outcome to see.

 > but the suggestion that the Script Editor is NOT the cause

(My emphasis added.) I was saying either SE or IDE probably INDEED is 
the cause, so I think we may disagree on that, unless one of us slipped 
in an extra NOT somewhere. And I certainly welcome disagreement; if your 
theory pans out I'll be just as happy as if mine does! Again, best 
wishes to you and I hope this will clarify any misunderstandings and 
avoid confusion to others.

Best wishes,
