Affects: gparted (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
After doing some changes to my partitions, the espresso window just
freezes and there are no more 'Forward'/'Back' buttons. After a while I
finally discovered that there was a dialog hidden behind espresso which
asked for confirmation of the changes; the dialog window did not appear
in the task bar and in the Alt+Tab window cycle list, so it is very hard
to discover it. However, it should be in the foreground in the first
place.
