          Priority: NOR

        ReportedBy: paul.drummond dsl pipex com

When I load KDevelop I get a KDevelop window with no contents then a seperate main window called "mdi_area_cover" which contains all the dockwindows and childwindows.  I've had this error before and posted a message to the mailing list along with a screenshot, see: http://lists.kde.org/?l=kdevelop-devel&m=108185261702286&w=2

I can reproduce the error as follows:

1) By default I use KDevelop in IDEAl Mode.
2) Change to Childframe mode then restart KDevelop
3) Change back to IDEAl mode then restart KDevelop
4) The "mdi_area_cover" window should appear.

Note this only happens with CVS - I can't reproduce this bug using stable KDevelop.  

Temporary fix provided by Jens Dagerbo replying to my post on the mailing list:

"Try this: Close KDevelop, open your ~/.kde/share/config/kdeveloprc file, remove anything that says [dockSetting.. or [dockSession (this is probably most of the file), save. Restart KDevelop. Hopefully, it should be back to normal now."

I find it easier to just remove the file altogether then re-configure KDevelop (works out to be quicker in the end!).
