Progress Indicator Revisited

[Bob Sneidar]

I know this has been hashed out before, but what did we decide? I am going through 3 nested loops, each of which puts some text into a field to indicate how far along in the process I am. Trouble is, nothing shows up in the field until everything is done. 

Is there a way to force the screen to refresh in a loop so I can see a progress indicator? I tried to send idle in 0 seconds each time I went through the loop, but no joy.
