FSX-MS Missing Windows

[fewtrils 0]

Sure hope there is someone out there that can help.

 

My problem happens in a variety of planes:

 

When in a default aircraft such as the Cessna 172.  I go to the view pulldown menu and select Instrument panel, then select either Main stack or GPS.  The window pops up very briefly then dissappears.  If I move my mouse curser over where it briefly appeared, although invisible, it is there and can be made visible if I undock the window.

 

When in a payware aircraft such as the PMDG NGX737.  I click on one of the MFD's, it also briefly appears then dissappears.  If I click in the vicinity of the location, then it will not appear but rather pop back into its proper location on the dash.

 

I am running 4 monitors, 3 are crossfired on matching Asus HD7770 cards and the single monitor is on its own its own ATI card

 

Any and all suggestions are welcome
