If you set a filter all files that match the filter are listed in the columns.
If you then klick on a row to change the sort order there are different files listed, that don't match the filter. But still the same amount of files is listed.
Example:
artist IS Beatles
There are 50 files listed.
Klick on any row to sort on this row.
50 other files are listed.
In addition, selection state isn't preserved correctly when the filter is changed and the newly-selected set of files overlaps with the previously-selected set.
Ideally, this should select only the files that were previously highlighted AND match the new filter, although this might be difficult to use in practice because of the interactive nature of the new filtering system.
I appreciate that it would be difficult. It would be better to clear it, though, rather than have it as it is at the moment (Unofficial2.44f just "preserves" the selections on a "displayed line number basis" - meaning that items that weren't selected become selected when the filter changes).
Accidentally posted in another thread when I meant to post in this one. I'm having the same issue still with v2.49b. Here's the crux of it (cut and pasted from other thread):
Hey Florian, sorry to raise a thread from old, but I'm having this problem with the new release: v2.49b. I filter on an artist or albumartist, etc and then sort by another field and a bunch of strange new mp3s show up...none of which match the filter.
