Dmex, appreciate your feedback. However, this is a brand new HP pc. Vista has given me problems from the get-go. It failed immediately...immediately upon installation of SP1. Now that I finally have it restored to pre-SP1, I'm still having the same problems I've had since I bought the pc 3 months ago. Graphics get totally skewed. Stock day-trading programs virtually unusable. Bottoms of charts suddenly appear concurrently at the TOP of the screen. Text and charts get broken up and pieces of one part of the screen appear at another location on the screen. Lists and boxes become suddenly opaque or transparent; e.g. try to pull up start menu but the items are not on the menu. Just using the pc this am for 4 hours, I've had to boot...without exageration...about 15 times. I HATE vista. Hate it!
