I upgraded to Vista Ultimate about a month ago and everything is running great (luckily no problems like everybody else) but one thing that i've recently found out is that for some reason it wont open and GIF files. I ran a test by creating a picture on photoshop and paint and saving them under jpeg and gif. The exact same picture was able to open as a jpeg but not as a gif. Is this a common problem? The error i receive is similar to this: Windows cannot find "File Name". Make sure you type the name correctly, and then try again. I even made a gif on my laptop running XP which runs find on the laptop but wont work in Vista. Any help would be greatly appreciated, you guys haven't failed me yet.
