This happens when Windows gets confused about the screen size as a result of
adjustments it makes for components that are docked at the screen edge.

Have you tried rebooting after making the change? Also, try dragging the
control (eg task bar) to a different edge and drag it back again.

If I change my screen resolution from 960x720 to 1024x768, my cursor
cannot reach the start button, the systray, and about 1/2"
of real estate on the left side of the screen.

When I change it back to 960x720, the cursor can reach everything.

What's causing this and how can I fix it?

Thanks.
