HD - my 'add/remove' in XP has been very slow to load for ages - same 'symptoms' - torch - so slow I often think the machine is locked up. It may be you are not giving it enough time? Don't know why, but try making a cup of coffee next time and see if it is still 'locked'. There is always 'Revo' too.
Win7 on the other hand............................no time for coffee
