Thanks for your comments. I also saved all graphs generated by loop and
selected graphs for combining with the commands of `graph use' and `graph
store' by loop. But, sometimes, I press a button for maximizing the window
size without a caution. This freezing problem occurs even when pressing
'graph edit'. My STATA 11 is 64-bit MP version on Windows Vista. I allocate
20g for memory partly because my data size is huge and partly because the
installed memory is 32g. I also simulated a simple case. I found that it may
depend on the number of graphs, the allocated memory size and the option of
graphic window. Actually, it does not matter with the capacity of processing
graphs in STATA. I sometimes hope to save the codes even when encountering
this freezing. Thanks again, and I will communicate with STATA.com later.
If anyone is wondering this problem, try it.

Subject: Re: st: Still Thinking or Resisting
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.
