[DUG] Debugging on TS

There are too many forms to do this on a per form basis. I have
finished testing the concept for this. I will add it to the generic
formclass that we use. I will test it later today. It does surprise me
that the app (and everyone else's app) does not fall over more often
even on fat clients.

Maybe you could change the btnclick to not close the form but post a
wm_close message to it?
