7.5PB4: When typing fast, quick filter can loose characters

[m^2]

I have a directory with 7741 files in subfolders. I just wanted to search for some files with quick filter in broad view and noticed a problem:
With such number of files, filtering takes much longer than typing. I can type 10 characters, wait, wait, wait...after a few seconds TC shows some 3 (it can be another number too) of them, the first is correct, but then TC skips a few, takes another ones, skips something again, takes another...

Also, I have a proposal: If I press backspace a few times, TC calls the filter for each button press for each file. If I press another backspace before TC finished processing the previous one, it could skip it and start processing another.
Caching results would be helpful too.

Completely agree.

I think some advices could be taken from here:

Sorry, Quick Filter has to work like this because it stops accepting characters if there would be no match.

No, it's another issue. It skips some characters. I type "celina" and TC displays "cin", although there is a file with "celina" in name.

I must agree with the bug report.

Quick filter has become very laggy and slow with beta4!

i got a folder with over 9000 files and beta3 worked really fast and i didint even notice any CPU load.

But with beta4 it has become really slow, sometimes misses keys if you are too fast and CPU hits 100% (50% on dual core).
Especially if you have typed something like

*test*2009*dat

in the quickfilter
and then press and HOLD backspace it takes ages to delete all the characters in the quickfilter (100% cpu again).
No problem here in beta3 either.

Confirmed!
Actually I didn't use the previous betas with many files, but now I tried and they not only seem to work correctly, but are way faster too.

I have checked now why it has become so slow: It's an error in the loading of the external search dll! I will fix that in the next beta. TC tries to load the dll again and again on each keypress...

Fixed long ago. Can confirm problem in the beta and that its fixed.

I couldn't reproduce this too, so it seems to be fixed here.

Great, thanks very much!
