[BUG?] AV after Alt+Tab pressed on text editor window

Allineer posted 4 years ago in HeidiSQL portable
1. dblclick on 'TEXT' cell in the 'Data' page - you should see the "Text editor" window.
2. press Alt+Tab for open any other window.
3. press Alt+Tab for return to Heidi.
4. I see "Text editor" window with completition window opened. why?
5. when I pressed Esc, I see AV.

This is issue #2640. I could go and silence this exception quite easily, but I would prefer a fix which also prevents the completion proposal from popping up. That thing is really hard to fix. I tracked down the exception callstack, but that does not reveal *why* it pops up, just from which line of code, but the reason is not really clear. Must be some internal Windows message cascading from some activation event into the SynEdit code.
