Hodgepodge

I installed Windows 7 and I must say I'm not open to change. I'll be typing and all of a sudden my cursor will just end up somewhere else, I don't have a "show the desktop" icon which I used ALL the time and it didn't come with a trial period of any anti virus software or MS Office. I think the cursor thing is because Windows 7 now has these keyboard shortcuts to navigate and I'm thinking I'm inadvertently doing some type of combo which moves my cursor to another part of the page. Anybody else have this issue? I've done it 3 times just ty... make that 4 times just typing this!! Still getting used to this new O/S, not sure about it. ;) peace
