Oh, it's very interesting indeed - especially when it happens while 
the application has captured the input focus...! :-D

Basically, it's what happens when some widget causes another widget to 
refresh, which in turn (incorrectly) causes the first widget to 
refresh, which causes... You get the idea! :-)

This can generally be avoided by separating rendering from control 
logic, so you can run logic first and then refresh things as needed. 
Unfortunately, it's not always quite that simple in real life.
