Yes, that helps. Thanks.

I find it quite astonishing that the "Debugger" option isn't on in the 
default configuration, though. Or actually, maybe I'm more astonished by 
the fact that this is even configurable - it seems to me that this is ones 
of the cases where it should be possible to implement one behaviour that 
Just Works, instead of adding yet another option...

I probably will.

What's even worse, though, is that I can't get this to work at all with 
the new framework, i.e. if I use the DSF process launcher rather than the 
Standard one (I haven't tried the "postmortem" and "connect to process" 
cases.)

Time for another bugzilla report, perhaps...
