I noticed the following in Win7.
In TC pressing Ctrl+s and entering a text string for filtering, only files containing the string in their file names were listed. Then I did one of the following:
Right clicked one of the files and chose “Properties”
Or, if it’s a text file, right clicked it and chose “Open with” --> “Notepad”
In TC Version 8.52a 64 bit, the filtered file list would remain until I came back to TC window and press Esc.
But in Version 9.0b16 64bit, the filtered file list would be gone in few seconds. Then instead the whole file list of this dir would be shown.
TC9b16: Quick Filter: filtered list disappears to quickly

It was caused by a different bugfix. This should be corrected in beta 17, please test it!
