I'm using a PC... is what I've installed for Tablet?.
Or is any other way to fix this?.

*** help! :(

I don't get it?. what you mean is I must chance my OS to Win7 or xp?.
Or do something in my photoshop?. If so?. How can I chance it in photoshop?. Can you teach me the process?.

We don't know what you've installed. Where did you get the software and what OS are you using?

I installed PS CS5 extended... I just got it from a friend, his using a laptop, I don't know if he has this problem too... my OS is Win7 already, don't know what should I do to fix this?.

That's likely the problem. Best to do a fresh install from the original DVD.
