poor subject line I know ...
Why is it when any application that uses .Net is displayed ( as opposed to minimized ) on your screen the memory usage for the app goes way up? For instance, Civil3D can eat up 400 MB of memory in a short time of working with it but if you minimize it the usage drops to 6,000 K! The new PowerShell is the same way, it has some nice features but it is a memory hog! That is until you minimize it.
