profile problems

IT had installed mechanical desktop 2008 while I still have mechanical desktop 2007 which I am using. There seem to be certain commands that do not work well.
1. When using the hole insert and select 2 edge, when prompted to click position the cross hair line do not show resulting in many cases of the hole being out of the part.

2. double clicking text for modification is useless and I have to use the properties dialogue box to edit text.

Our IT keeps saying that the OS (windows xp) profile has become corrupt. Has anyone ever encountered such problems? got any idea what it might be?
