Situation:

	Several windows opened for my application
	Using some for copying between on offscreen grafport

Problem:

	When a dialog pops up, then is closed, the obscured
portion of the windows are also erased, so I need to update
them.  I catch the update event, check which window via
FindWindow(Where).  Then use if structure to see which 
window to update (as each may be different).  Then I do
what is need to update the window.  

Catch:

	The window only actually gets updated when the mouse
passes into the windows content region.  And it will keep
repeating the update until the mouse is moved out.  This 
occurs even when the window doesn't need updating any longer.

I call Begin and End update surrounding thje code that does
the update for each window.  So why is the update event not
being thrown out after I do the update, or likewise, why is
it continually getting an update while the mouse is in the 
window?

Should I be finding the window to update differently?

Thanks in advance.
