Ok, this helps explain why moving the mouse causes the idle event:

"Note that, unless you do something specifically, the idle events are 
not sent if the system remains idle once it has become it, e.g. only a 
single idle event will be generated until something else resulting in 
more normal events happens and only then is the next idle event sent again."

But I'm still confused about why *not* moving the mouse still allowed 
the progress bar to increase (although that behavior has stopped now for 
some reason).
