This is worth investigating but I wonder how deep this goes. IDL still
needs to process events whether it be xmanager or whatever is *really*
managing events and I am not convinced that xmanager is the real problem.

The suggested work arounds don't really address Randall's main need for
manipulating his data sets. You can force an application to draw before it
goes into the event loop but it still won't accept input or redraw. Maybe
an approach like this would work:

PRO TEST
DATA = BESELJ(SHIFT(DIST(40),20,20)/2,0)

not_ok:
stop
FSC_SURFACE, data, /block, ok=ok
if (not ok) then goto, not_ok

END

You could issue a stop, play with your data, then issue a .cont where you
would jump into your OG viewer. Depending on how you choose to proceed, you
could stop again and play with the data or you could continue on. Some
minor modifications to your favorite OG program will be in order. Not
pretty but functional.
