I have tried all of the above suggestions. Adjusting the resolution is not the problem. My problem is that the top and bottom tool bars run over the right and left side of the screen. I have tried to move them in but don't seem able to accomplish that. Also, on the desktop, the shortcuts run over the left side. If I move the resolution, then the toolbar at the bottom is really over the right side.
There must be something simple that I can do to fix this. I just haven't been able to do it.
I also tried tapping the +_ keys in the toolbars but that didn't work either. Sorry to be so helpless. Pat
