I'd like to add a more detailed description of what happens:

In my settings, I have chosen PTBatcherGUI as 'Processor'.
I have also chosen to execute stitch jobs instantly and to show detailed 
progress information, but I haven't chosen parallel execution or 
deletion of existing images.

- when I start the stitching for the first time, the batch
   stitcher is launched and if pictures need to be overwritten,
   the 'delete existing images' dialog shows.

- if the batch stitcher is already active from a previous use
   and I ask for a stitch to be done which would require images
   to be deleted, then the error occurs and the 'delete existing
   images' dialog is hidden. At the same time, both the batch
   stitcher's window and the stitch log window (which is empty)
   remain unresponsive, until I Alt-Tab to the 'delete existing
   images' dialog box and okay or cancel it.

I can get to see the dialog box when it pops up if I move hugin's
window out of the way before I press 'stitch'- the dialog always opens 
in the center of the screen and normaly my hugin window covers that.

So the problem seems to be that if hugin is in the foreground and
PTBatcherGUI is in the background, the dialog is hidden by hugin's 
window. Maybe bringing the batch stitcher to the foreground when
it receives a job and immediate stitching is activated would mend
the problem.

Title:
  some modal dialogs hidden behind other windows

Status in Hugin - Panorama Tools GUI:
  New

Bug description:
  for some time I've been annoyed by a quirk in hugin: some modal
  dialogs are not displayed on top of all other windows, but remain
  hidden behind other windows on the desktop. This has the effect that
  hugin becomes unresponsive until one Alt-Tabs to the dialog in
  question and responds to it. I've noticed this behaviour with two
  dialogs:

  - the stitcher dialog asking whether existing images should be deleted

  - the dialog reporting the return code of a python script

  I doubt this quirk is system-specific - the python script response has
  behaved this way for a while, but it only mattered when I ran woa,
  because the other plugins respond quickly, and the dialog is at least
  displayed on top initially - woa takes much longer, and if I do
  something else in the meantime, the dialog is hidden when it finally
  comes up. With the stitcher it's much more annoying: the dialog never
  even shows on top and has to be looked for in the list of available
  windows. I suppose the problem has been newly introduced by always
  using the batch processor for stitching.

  I reckon wxWidgets has a simple flag somewhere for dialogs to display
  'always on top' which has simply not been set, but I haven't
  investigated.

  Currently I'm using Kubuntu 11.4 on an intel system:

  Betriebssystem: Linux 2.6.38-10-generic-tuxonice i686
  Architektur: 32 bit
  Freier Speicher:  2000244 kiB
