A Ghost in the Computer

["Stephen P. Molnar" <s.molnar@sbcglobal.net>]

Perhaps this is not the appropriate forum for this problem but the 
Debian List has been an invaluable resource over the years. I happen to 
be a Chemist and although I've been using computers in my work since the 
1960's, I am not a computer person, only a user.

I am running Debian Stretch on my main computer.  I have an AMDFX-8320 
Eight-Core Processor on a ASUS MSAR2.0 Moptherboard and 8GB of running 
XFCE4.  I an encountering a rather odd problem for which I have no 
explanation.

If I have more that three or four apps open at one time, all of the 
non-active windows will pop open at random and predictable times with 
the result that no one window will be useable, unless I close every app 
that's open.

This performance is rather annoying and rather disruptive.

Any suggestions will be appreciated.

Thanks in advance.
