FWIW, I had a similar problem several months back. I was generating a
fairly large number of graphs within nested loops and then combining them.
It all worked fine until I tried to maximize the graph window, which
would cause my computer to crash.
I sent Stata tech support the data and code: they were unable to reproduce
the problem on their machines. I subsequently re-ran my code on another
machine, and ultimately on a few other machines, with no problem
whatsoever. The problem persists on the machine which originally produced
the problem.
My best guess is that it is either a hardware problem or some difficulty
with the graphics-handling part of the OS that causes this.
As a work-around when I have to use the problematic machine, I do what
another person suggested on this list: I export the combined graph and
then open it in a picture-viewing application.
I suggest you send your data and code to Stata tech support. If they do
find a problem in Stata, let the list know--there may be others who have
encountered this. But, if I were you, I'd also check and see if the
problem is reproducible on another computer.
Good luck.
