For some reason I notice that the Runtime Broker process takes up too much memory. Close to 300mb. Also I see two of them running now. I don't recall what I did but at this point its memory use slowly went down to about 15mb. The 2nd instance is taking about 1mb.
During high memory usage period the surface is not behaving properly. It does not react to clicking links for example. Clicking a link in Mail does not bring up ie.
Are you aware of this?
Also I once killed that process and nothing bad happened. I cannot figure out what its for.
