live code seems to gratuitously unlock write permission for directories

OK, I got slightly lost in this thread - we've gone off to solve a 
work-around to your problem, and I'd like to go back to the problem itself.


If I understood it properly, what you;re seeing is that setting the 
permission of a directory to disallow write *should* prevent you from 
saving a stack within that directory - but it doesn't.

So I decided to write a small test stack that did just that, and see how 
it performs. And it does just what I would expect (which I think is the 
same as you would expect :-)

I know it's unhelpful, even annoying, to be told "it works OK for me" - 
but it works ok for me.

Could I ask you to download my simple stack, and try it out in your 
environment - ideally on the same directory - and report back on what it 
does ? Hopefully this will isolate whether it's your 
OS/filesystem/environment or something else going on in your scrips.

It's at http://tweedly.org/downloads/checkpermissionsettings.livecode

very simple stack - 4 buttons

  - one let's you specify a directory

  - one checks the permission of that directory and write that to the 
msg box

  - one removes write permission on the specified folder

  - the last one adds write permisison.

I actually saved this stack within the folder so I was testing something 
as close as possible to what I thought was your situation.

So you should find that after specifying the folder, you can check the 
permissions, save the stack, remove write permission, check permissions 
(and see that it's gone), then try to save the stack again - and it 
fails. Then add wrote permission back again, chek permissions and then 
save - works OK.

Thanks
