[Cuis-dev] UI freeze fix

[Casey Ransberger]

If I’m reading this right (and I may well not be) this seems like a really great change. One of the things I ran into constantly when I was trying to make the system theme-able was that when I made a mistake, I’d hose my whole image, because when the debugger pops, it uses the very windowing system my mistake was in. Upshot: screen fills up with debugger windows and grinds to a halt. So, start with a clean image, load the changes I’d made up until the one that exploded, then try again. 

It was kind of a pain. This seems like a better idea.

I think it is better to show the pre debug window in those cases because: 1) opening the debuggers is confusing because sometimes you do not  realize it is a different debugger (specially newbies) 2) because if there is an error in the debugger, opening the debugger generates a loop but opening the pre debugger window can prevent that loop for happening.
