This "Save as" issue has been around for a long time(4/5/6/7/8). You can "Save 
as" and have no problem or suddenly the " already a stack in memory, please 
purge.." pops up or other times it happen immediately. And yes it always saves 
the stack correctly. I do version control by either "Save as" and then close LC 
and re-open or by coping the stack outside of LC and then do a standard issue 
"Save" (my preference).

This seem to be one of those hard to pin down things like the "Variable Shadows 
another..." issue.

I don't see a bug report for this.

Subject: Bad Crash on Windows using LC8

yesterday I was mentoring  a newbie with LC 8 stable on Windows.

Via Skype, he shared his screen. and we went throught the process of building a 
stack, making groups setting them as background, putting scripts into the stack 
scripts and calling from button etc.

He uses MSWord and PowerPoint and Excel most of his day… and has the habit of 
doing frequent backups by using "Save As" and adding/appending a version 
number-date in the file name and then keeps working in the new document.

He saved the stack then did a "Save As" and then "the pea soup hit the fan" as 
LC when into an infinite loop saying that there was already a stack in memory, 
please purge.. Cancel, Purge Save buttons in the dialog were all unresponsive 
and we were sitting there a bit aghast as LC keep looping and flashing through 
this, re-rendering/flashing the stack in the background and the dialog box on 
screen. Attempts to hit cancel did nothing. Control-dot interrupt did nothing…  
He had to kill the process.

Fortunately the stack had been "Saved As" and so now he did have the document 
in it's last iteration + the one he had saved as… and neither were corrupt. But 
it was a scary moment… and not a very good experience for a new user of the 
software.

I am unable to replicate this on my mac.. though I have had a number of 
instances where if you choose "Close and Removed from Memory"  later in the 
session if you open that stack the IDE tells me that the stack is still in 
memory and do I want to purge it… this seems somehow related.

Anyone else getting this? has it been reported already?
