I've been having the same issues with cisvc.exe pegging out on my TabletPC. It is very random and acts up even if I'm not in an application. I had this issue in the past when I installed windows desktop search about 6 months ago.

My fix was to uninstall windows desktop search and go with googles search. The issue now is that the indexing is so closely tied to Office 2007 that it's not the best option.
