On a Vista Business PC with SP1, the Remote Desktop client will use
excessive amounts of CPU when the screen refreshes. For example, if I
remote desktop to a server and try to use the DNS admin MMC, whenever a zone
is refreshed, CPU on my PC will spike. the mstsc.exe process (remote
desktop client) is the prime consumer of CPU.

Is anyone else seeing this? Is this a known issue?

Any insight is greatly appreciated.
