In case this might be helpful to someone... I was having problems with Mercurial yesterday which was due to repo's hgrc owner being Adminstrators, not Pete. After going into the Win 7 security properties, adding myself (Pete) to the list (with full control), and then using chown to change the owner to Pete my problems went away. Sensing that the problem was due to the use of Cream/Vim I edited hgrc with Cream/Vim and the ownership of the file changed back to Administrators. When Cream/Vim starts up I was being asked to give it administrator privileges. So editing the file with administrator privilege was the problem. I went to the Compatibility tab of the property sheet for Cream/Vim at c:\Program Files (x86)\vim\vim73\gvim.exe and unchecked Run this program as an administrator. That fixed the problem.
