This usually happens when gdb fails to set an inferior pid (which is/was 
gdb's goofy way of knowing whether an inferior exists), but it could be 
anohter error getting in the way. If you enter "tk ManagedWin::open 
DebugWin" in the console window, it will open a debug window. Clear it 
before you click run and send the results after you have clicked run and 
it fails to do anything.

Can you also send the results of typing "tk gdb_target_has_execution" and 
"tk set ::gdb_running". This will tell us if inferior_pid is set.

I've tried this on CVS head, and it works on my ADS executable on the 
simulator. You could simply upgrade to 5.2 or 5.3 or just use CVS head 
sources.
