Quirky Full-Screen Mode

I don’t if other people have had this problem. I did a search and couldn’t find it. I was playing around with full-screen-mode and I inadvertently resized the paper width to narrow. When I tried to get it back to it’s original size, the little slider kept reverting back to narrow. I somehow managed to get it back to it’s original size, but now the problem is that when I hit the paper position, for left, it won’t let me switch back to center or right. I hit the scroll bar and it pops up, but it doesn’t “catch” and when I try to type on center it won’t take.

Never mind…I figured what the problem was: my mouse. I was using a wireless one and I forgot that I had the same problem with Word a few months back.
