Sage 100c window will not open

SUGGESTED

So this happened to 2 machines today.  Multiple displays, log into Sage 100c, and no windows open.  You can see the icon in the task bar.   Old fix, change display and only open on primary monitor worked on one machine.

For the other machine nothing is happening.  PVX is running.  We even disabled the secondary  monitor, no luck.  And I did a workstation reinstall.   Nothing.

We UNINSTALLED the 2 windows updates from last night and restarted the machine.   Still no luck. 

You open SAge 100, log in, and then NOTHING.....   If you try again, it says a Business Desktop already started.  And PVX is running...

Anyone else have this issue with the latest windows 10 updates ?

Thank you

Lisa
