[ms office - 2010] Office 2010 on Citrix

[DSapseid]

Bit of a weird one here, i upgraded machines to office 2010 over Easter and all is fine apart from powerpoint on my thin clients and provisioned thin clients. I'm using Citrix Xen App and Xen Desktop.

 

When you open powerpoint the screen starts to do flicker black like its changing resolution then it will sometimes sort itself out. Other times the screen goes black but if you do Ctrl+Alt+Del then press cancel its fine or you when you do that the resolution is like 640x800 or something similar.

 

Its only powerpoint and only on the citrix based machines. Its Office 2010 SP1 on XP.

 

Any ideas gratefully appreciated!!
