Presuming you are running XWin in multiwindow mode, I think you're
running into this issue:
We believe that it is not a bug in Cygwin or Fedora, but in gtk+-3.x
itself. You aren't seeing this with Fedora 14 because that still uses
gtk+-2.x for most apps.
A new "feature" in gtk+-3.x is that the unused portion of any menu- or
toolbar can be used to grab and move windows as if it were part of the
window decoration. XWin's multiwindow WM implementation doesn't provide
the necessary functionality for that (whatever that may be, we're not
sure yet), so we're particularly susceptible, but as shown in the bug,
this can be reproduced purely within a Linux environment.
As you'll see we have yet to receive a response from upstream. Until we
can get this fixed in gtk+, or implement the necessary feature in XWin
to avoid the bug, the workaround is to use XWin in windowed (desktop)
