[TC 9.0rc3, 8.52a] TC hang with quick view and quick search

[MaxX]

You'll need:
1. TC 8.52a or TC 9.0 rc3
2. sLister.wlx + SumatraPDF.exe
3. some PDF files

To do:
1. Start TC
2. Go into some dir with PDF files
3. Open quick view mode by Ctrl+Q (cursor is on highest ".." position)
4. Open small quick search box via [cm_ShowQuickSearch] or hotkey
5. Type some first letters of any existing file
6. (now TC moves cursor to one of these PDF and hangs)

Tested combinations :
TC32 8.52a + sLister.wlx 1.1.2.0 + SumatraPDF.exe 3.1.1.0.10417z + Win7 SP1 32-bit
TC64 8.52a + sLister.wlx 1.1.2.0 + SumatraPDF.exe 3.1.1.0.10417z + Win7 SP1 64-bit
TC64 9.0rc3 + sLister.wlx 1.1.2.0 + SumatraPDF.exe 3.1.1.0.10417z + Win7 SP1 64-bit

Don't know, is that a bug in TC or in plugin, but it makes TC unusable until taskkill...

It happens only when starting the search from the ...

Unfortunately it is a plugin bug, and there is nothing I can do about it. I already added a fix for a similar problem:

26.10.16 Fixed: Close quick search dialog when user presses Ctrl+Q, otherwise some plugins like SLister can hang Total Commander (32/64)

But I can't just disable quick search every time you press a key in it while quick view is up, that would make it unusable. So far only sLister is causing this problem.

Understood.

Actually I found a solution now:
1. Disallow closing of quick search window
2. Set focus in active file list
3. Load file via plugin
4. Handle all pending windows messages
5. Set focus back in quick search window
6. Handle all pending windows messages
7. Allow closing of quick search window

This method also works when user presses Ctrl+Q in quick search, so I no longer have to close it to prevent the hang.

Well, the fix had one negative side effect:

But that will be easy to fix.
