Help! I'm trying to write an XView program but can't seem to figure out
something. I am writing an program to control a camera. This program allows
the user to set parameters ( ie exposure time ). I defined a "Go" panel
which starts the camera. When the user selects "Go", I want to create a
window which displays a count down timer, camera status  and has a 
"Cancel" panel button to stop the camera. This seem simple but .. 

	- I don't want to allow the user to interact with the camera using the 
	  other panel buttons while its taking a picture. If I return control
	  to the notifier the user is free to interact with the program's 
	  other objects.

	- I like to print to a window the camera's status information but new
	  window can't appear and text written to a window is not updated 
	  until you return control to the notifer.

I'm new to event driven applications. Any Ideals?

Thanks,
