#2640 AV on alt-tab when in popup editor

[Anonymous]

Originally created by: bas...@hotmail.com

What exact steps will reproduce the problem?
I'm not 100% sure, but it must have been something like this:
1. Open a query window and type a query. I'm not sure if it's important to leave the cursor at a specific place or not
2. Go to the data tab and find a table with data
3. Hit F2 on a (text)field to get the popup editor
4. Alt-tab to an other program (document with text or so)
5. Return to Heidi with alt-tab and find the auto-complete proposal window on top of the popup editor and an AV.

(While trying to reproduce it I only got the auto-complete proposal in from of the popup-editor, but no AV)

If I'm at the query tab and go to About -> Check for updates, the auto-complete popup also shows when alt-tab is used

What was the expected output?
No auto-complete proposal on alt-tab and no auto-complete proposal in in from of the popup-editor. Should the auto-complete proposal be active on the data tab?

What happened instead?
Auto-complete proposal on top of other window + AV

Version used?
HeidiSQL revision: latest, 3983
MySQL Server version: 5.1.46
Operating system: Win XP

I can now reproduce it: If you use the escape key to dismiss the auto-complete proposal it stays on screen and the AV pops up.

Confirmed, saw that two a couple of times.

The autocomplete dialog is also there if you are at a query tab and open the About->"Check for updates" dialog. If that window is open (and there are new updates), alt-tab results in the autocomplete dialog. Pressing ESC doesn't cause an AV though.

I was hoping this was fixed yesterday in [r4104], when updating SynEdit. But I can still reproduce that, using the Esc key approach.

Please, can the priority of this be raised? The bug exists for a very long time

Got it. See issue #2351 and my modification in [r3763] to enable the Windows Flip3D feature. "MainFormOnTaskBar" seems to have this effect when returning to the HeidiSQL window.

[r4371] removes that MainFormOnTaskBar again, and fixes this issue, while it breaks again support for Flip3D, but who cares...

Status: Fixed

Again, an attempt to fix this crash and unwanted popup window without breaking the Flip3D feature, in [r4530]. Please shout if you again have crashes or the popup now. Sorry to be a bit experimental here. I just got another issue report (issue #3342) which requires MainFormOnTaskBar to be activated.

Mouse clicks in the completion proposal don't work any longer now. I need to fix that... sigh.

[r4555] should fix the disabled completion popup.
