Did the update of something cause this?

I don't see any other reports of anything like this.

It might be worth investigating what state the windows which have 
disappeared are in.  Are the X windows in a viewable or notviewable 
state, according to xwininfo?  You could use spy++/winspector/etc to see 
if a Windows window exists and is hidden or not.

Is this linked to any 'virtual desktop' type software?
