Point to any part of the Taskbar EXCEPT the Start Button. Hold in left mouse button. Drag pointer to center-bottom of screen. Release mouse button. Voila!
Thanks but that's what I've been doing for hours, whaaaaa. Ok, I left clicked in the gray area of the start menu, white arrow remained, held it down left mouse button while moving white arrow down to center-bottom of screen, and released mouse botton. Zip, zero, nada, and for the 3847th time the start menu remained on right side of screen. Short of pulling the plug, I still need help!
