I have run across an interesting, but apparently not uncommon, problem.  In
a program that I am writing, I have found a way to freeze my mouse pointer.
Unfortunately, this was not what I was trying to do.  Everything else still
functions properly, such as using menu keys and the like.

What I would like is a code segment that I could include as a menu item that
when called (via MenuKey) would unfreeze my mouse.  I am using turbo pascal
macintosh (which I really enjoy, but that is another story), Jut I can deal
with a code segment from any language.  A call that I could make from MacsBug
would also be wonderful.

I suspect that the problem involves the vertical retrace interupt becoming
disabled, but I haven't yet delved into that chapter of Inside Macintosh.

I do realize that using TMON will solve this problem, but I am not ready to
invest in a new debugger just yet.
