Hi Brian,
I tried testing this behavior today and I am not able to reproduce any refresh/repaint performance issues in Mobile Project Center when testing with VMware WinXP SP3, ArcGIS Mobile 9.4 Beta 2 configuration. I would like to look into this further for you but need to first gather some additional information.
What video adapter type is used?
Are the latest driver updates installed?
Does the behavior occur with other applications?
What is the Build # for Mobile Project Center (MPC button > About)?
What is your VMware version & Build info (VMware Player > About)?
What is the memory allocation?
Are there messages in the VMware message log?
How many VMs do you have installed to your VM directory?
Thanks,
Denise
