Toolbars sometimes don't launch

[Gintaras]

And all window triggers stop working? Please test the same trigger type with a macro or function. If it does not work, try menu Tools -> Output -> Log -> Window events. What text it adds in QM output when you activate a window? Should be like this:

active 11731346 "Notepad" "Untitled - Notepad"

When you run a program, should be like this (or more lines):

created 11796882 "Notepad" ""
name 11796882 "Notepad" "Untitled - Notepad"
visible 11796882 "Notepad" "Untitled - Notepad"
active 11796882 "Notepad" "Untitled - Notepad"

If window trigger is "Created and active", try to replace to "Active".

Possibly upgrading to QM 2.4.2 would fix it.
