the screen resolution settings and compare those with the native resolution of your monitor. If you don't know the monitor's native resolution, maybe you could supply the brand and model and someone could look that up. Also mention your operating system...XP Windows 7, etc. The "right-clicked something" was what messed things up and the fix would be to undo what was changed.
Yesterday, my husband accidentally did something to the computer that made the page too large for the screen. I have tried making it smaller, moving it, but it only makes one side disappear a little. He said he thought he right-clicked something. I have been all through everything I can think of and still no luck getting it back to normal.
Is there anyone out there who can help??
