Periodically I notice PowerShell seems to take forever to finish doing whatever it is I told it to do until it occurs to me to "wake it up" by pressing enter. This is not the fault of any one process as best I can tell, as I have even run custom apps that just log their output to the screen every few seconds and even in these cases, PowerShell will stop doing anything after a while until I "give it a kick" by pressing enter.
Any ideas what might be causing this?
