Disappearing Taskbar?
 

I'm having something weird happen - everytime I switch my monitor resolution from 800x600 to 1024x768 my taskbar at the bottom of the screen & all the open windows I'm working with disappear & I can't get them back until I switch resolutions. At every other resolution they don't disappear, even 1600x1200. I usually like to be at 800x600 but occasionally use 1024x768 but now I can't use it. Any ideas? :(

Have you tried adjusting your monitor after you switch resolutions? The taskbar is probably there, just a little bit off the screen.

Sometimes you have to manually adjust certain monitors to make sure everything is centered.
