Dissapearing GUI

["Luis A. Montes" <luis montes dslextreme com>]

Hi

I wrote a small gtkmm application using MSVisual C++ 2005 under
WindowsXP. It is basically a wizard with a working thread talking to the
hardware and a gtkmm gui showing the progress. It's been working fine,
mostly. But yesterday the GUI stop repainting. The worker thread kept
running, the window would minimize, restore, the mouse would change if I
hover over a text field, and if I click on the 'x' to close the
application a confirmation MessageDialog spawn from the on_delete_event
would show up. I could (blindly) copy and paste text from a TextView
into Notepad, although it was not changing as it should. But all the
client region would just keep whatever background the application window
happened to be over.
I'm just wondering if anybody would have a guess at what stopped
working. I distribute the app with a minimal gtkmm/gtk+ set of files
hand picked from the gtkmm-win32-devel-2.10.11-1.exe binary
distribution. It could be missing some files, but I would think that in
that case the app would just crash.

Thanks
