Keystoke problems...major issues!

[Kfentress]

I have a Dell with Vista installed....and am awaiting Win 7 upgrade, but I have a problem that needs addressing now. What I am describing occurs in any program...Word, IE, Works, Outlook Express, all of them. The problem is when I am typing in any program, (including this window even as I type this), and the keystrokes I'm pressing ,in SOME combination I can't figure, out shoot me into another window meaning that another new window will open and I'm then typing in it. If that doesn't occur, then it will randomly force my cursor and typing to another area on the window...usually in the middle of text already typed making another huge mess It is also changing the font to bold, or underlined, or italics at random. Other issues include that suddenly all copy with be selected, or if I am in email, I have had the email send several times simply when I hit the "return key." I am about to loose my mind with these issues!

I am at a total loss. Yes, I am positive that it is not my typing skills. I am a freelance writer and this is only occurring on this laptop that has Vista. I have checked for Virus', adware, spyware, etc. Even registry changes but none of those are the case. I am lost and it's getting to the point where my laptop cannot be used.

ANY advise, solutions, or answers would be more than appreciated. Is there a "hot key" issue with Vista? Whatever idea's you may have...I am wide open to anything to resolve this issue.

Thank you so much!
