Fvwm 2.5.1[02] gets stuck sometimes, always while raising or deiconifying a
Mozilla window via WindowList command.
When fvwm gets stuck...
- CPU usage reaches near 100%
- Mouse pointer remains in the set "CursorStyle MENU"
- Mouse moves but clicks do not respond
- Keyboard is also lost
- No windows is raised/lowered or a page is changed
WindowListFunc & related functions and focus & placement related
styles are...
