Could you pull this plug?

I've configurred Lazarus to use the standard gdb. I'm using a csv build of this morning but had the same with a csv build of a few days back.
While I'm at it, pressing ctrl-f2 to reset my running program doesnot work.

I'm using KDE with multiple desktops and ctrl-f2 switches to desktop 2 (as ctrl-f1 switches to desktop 1, etc etc. )
