IDE crashing on Windows 10

I don't know how C modern programs handle errors but on VAX VMS there was a
handler available to all languages. It was named
"lastChanceExceptionHandler"(always sounded like the OK Corral). This
allowed the program to possibly save work, gracefully shutdown and produce
crash logs. This new era just crash and go away is astounding. Is there no
way to trap severe errors?

LC 9.6.1

I can be in the Script Editor typing away. I move the mouse to click on
another line of the script. Blammo. LC crashes.

Any idea how this can be pinned down?  I can't see any pattern.  The only
plugin open is Geoff's Navigator. There's only a few tabs open in the SE.
The total size of all scripts in the stack is probably 1000  lines.

I'm not doing anything fancy with fields or images. The portion I'm working
on is just posting to a URL, then calling jsonToArray on the results.

It's baffling me. And it doesn't look good for a professional tool.   I've
seen this kind of thing before with red bullet breakpoints (just clicking on
one of those to set/unset it) could cause the IDE to crash.
