I think the weirdness was me

A couple of days ago I mentioned that I was having some problems with loading symbols for a common controls dll. I’m now pretty sure that it was my problem, as usual, rather than someone elses. I’ve reworked my process startup controlling code and now set and clear the breakpoints in a more reliable (i.e. less hacky) way and things are behaving themselves again. I think I was failing to stop one of the threads properly and that was later causing problems.
