Sure, I use Xnest et al. quite a lot. The problem is: to use the debugger I have to focus it ruining the debug session. I rarely start a separate X server because XFree 4.x crashes or hangs most of the time when I do this (for debugging). > Or have I > been away from working on fvwm for so long now that my memory of the pain and > difficulty of debugging certain things like focus has faded (always a > possibility) even using the above tools? > > >> If no one has any ideas off the tops of their heads, I'll look into it > >> myself tommorrow. > > Which I did, but didn't get very far.
