Scrollbar misbehaviour in Dir with many files

[ErikG]

A strange behaviour occurs with the scrollbar when a directory contains many files.
I have a directory containing over 80,000 files. When I drag the scrollbarbutton down I see the starting letter ascending from A to R and than the files start again at A ascending to C when moving further down. There is therefore no way to reach files with starting letters from S to Z. (In alfabetical sort mode. Other sort modes behave in the same strange way).
When I stop at R and click in the lower scrollbar it works fine but that is rather slow with so many files. When I arrive at a file with a starting letter from A to Z in this way just touching the scrollbarbutton with the mouse moves me back to the start of the alfabet somewhere between A and C.

I noticed this anomaly also in earlier versions of TC than 7.56.

Quick check at MSDN suggests that in some cases scrollbar range might be limited to maximum of 65535. Mr. Ghisler probably didn't think that anyone would ever need to have more files in the same directory. It's really crazy amount of files. :)

This may be possible frequently for synchronization.
This is already in to-do list of Author.

Do you use Windows 7?

From the above German topic: I could reproduce the problem with TC7.56a in Windows 7 but not in Windows XP.

It's indeed a bug of the themed scrollbars in Windows 7. If I remember correctly, it works when you turn off theming.

Right. Windows framework. i was close with guessing

i can live with that limitation. turning off skinning is not an option.

Thank you.
