Summary: Changing "file type" with scroller does not register Product: Wine Version: 0.9.12. Platform: Other OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: wine-gui AssignedTo: wine-bugs@winehq.org ReportedBy: mccpat@gmail.com
I used FASMW (http://flatassembler.net, Win32 version) with this example.
If the file filter is changed by using the mouse scroll wheel, without opening the drop-down box, the open file dialog does not redisplay the files with the new filter. However, if you change the file filter by clicking your mouse (including dropping the filter box down) on a different filter, it will.
