Thanks for reporting this issue.

It seems that a change in 1.17.2-1 had the unintended side-effect of 
breaking working with VirtuaWin and Dexpot (windows which were hidden 
when switching to another virtual desktop become lost)

While this can probably be worked-around in the virtual desktop software 
configuration, I'd like to try to fix it.

I've built a snapshot with a potential fix.  Perhaps you could try that 
and see if it improves things for you?
