And this confirmed the existence of another problem, which I had been
suspecting existed: when I set breakpoints in programs in IDL's
library, they get ignored. It is not an issue of not putting them in
the right routine by changing the source code (in this particular
instance, of graphicswin__define.pro). And when I move that file from
the IDL library directory to my own, the breakpoints work. Is this
intended? Is there a way around it (besides moving the entire library
directory somewhere else)?
