To Butzilla and Vampire Hunter G- I thought the Direct Application Launch Button only worked in VISTA not XP. So maybe when you downgrade to XP, you might just have two yellow marks. Any ideas?
Just install all the drivers posted in this thread, make a folder, put all the drivers in it, right click your yellow marks and update. You may have to spend an hour or better doing this but it will work.
Note: to date the power off feature when you close your lap tops lid still has not been solved under the "upgrade" to XP. LOL
