Ray, take it easy man. Your last post sounds like the kid who goes home pouting with his ball. I don't mean any offense, and I know how frustrating it must be.

There is likely something very simple going on. Did you enter your email address in the form: name@gmail.com? And remember, gmail is not going to be exactly like your previous email account, there will be a bit of a learning curve.
And I wouldn't be so worried about the scroll bar, it will show up we promise.
Don't leave SMC on account of gmail! Try doing a google search for some of your question/problems too. You are not the only one to have questions about how to use gmail.
