Trio8800 + Group Series - WebEx - 2nd Monitor black screen sometimes...

We've found Trio F/W & Group Series very stable.  No call dropping, no camera reboots/core-dumping and Trio audio is perfect.  However we've noticed about once a week, when someone pushes a presentation to the 2nd Monitor, it is sometimes black.  If they stop presenting and repush, it's still black.  if we hang-up the call, and go-back-in it's still black.  Other pushes from PCs work fine...


Today we isolated the failure behavior when someone on a Cell Phone shared the "Portrait" screen of a new APP under development - we got a black screen.  Everyone else at home, or elsewhere, saw the APP screen push but not the folks in the meeting-room with the Trio/GS.


After the call, we created a test WebEx call to myself and my Android phone.  I installed the mobile WebEx client and the basics worked fine (audio and video) - but when I shared (say) a JPEG picture from my photo library, ONLY "landscaped" pictures worked/pushed/showed-fine.  If I pushed "portraits" - I got a black screen 100% of the time.


If I tilted my phone in landscape at the home page, that pushed.  If I stood-up my phone in portrait and shared my home screen (to the WebEx call), I got a black screen (all the time).


Is there known issues with portrait vs landscape screen pushes?  This would make sense why PCs (typically in landscape by default) work fine and tablets and cells (may?) have problems.


Yes we can upgrade to the latest but any help to resolve this would be appreciated.
