I'm running Debian/Woody 2.4.21, gdm/Sawfish WM.

The problem has now recurred with two pieces of software, as far as I know, development of the two is mostly unconnected.

1st time:
dctc running the dcgui app as the UI. It looks like the UI fails to refresh after a while, displaying a grey & white screen, which does not update. As best I could tell, dctc continued operating normally, and I could run it from command line.
Rebooting X or the entire system has had no effect.
Uninstalling and purging all config files for both dctc and dc_gui, and then reinstalling has had no effect.


2nd time:
dcgui-qt (http://dc.ketelhot.de) which uses clibdc0. After some time of usage, same problem. Screen stops refreshing.

Suggestions? Similar experiences, anyone?

Thanks.
