I have installed the 32 bit version of the Exchange 2007 Management console on my citrix server. If I RDP to the server and run it, everything works just fine. However, when I publish the msc through Citrix, the snap-in crashes. I believe it may be something with the animation of loading circle because the tabs that don't use that work just fine and it puts a large red X where the animation should be.
The error is:
This snap-in performed a non-valid operation and has been unloaded. To continue working with this snap-in, restart MMC or try loading the snap-in again.
Exception Type: System.NullReferenceException
Exception Message: Object reference not set to an instance of an object.
