I'm a she, not a he and not a Tom! :lol: and I'm actually a XP personalization addict(among other things) if you wanna know! :lol:
I don't think 7 is better then xp...(from my point of view , is on the contrary...)
But anyways, do a search of ListviewShadows (exacly like I write it!) in the HKEY user config and also in the HKEY local , it has to be in there somewhere...
By going to Edit>Find next and keep pressing F3 until it finds it.
If somethings fishy, and dosn't find it then maybe it's better to create a key yourself, by right clicking on Explorer and New>Key and name it Advanced. Click it .On the right empty space , right click and create a new Dword value yourself , name it ListviewShadows, and make sure it's set on 0x00000000.
Don't change anything else in there!
If that doesn't work, I agree with my upstairs neighbour, ksiemb , to make a new user and apply your personnal settings, then copy all your desktop and My documents to the new user...
If I'll think of anything else I'll let you know!
