Thanks for the suggestion. Here is something new. I got a new laptop to use as a backup/second unit for the Hoster. I just connected it up to a 23" monitor (widescreen at 1920x1080) via HDMI connection. Everything is working fine, including the extended desktop. However, it's now showing the exactly the same problem on the singer screen. This is just a single monitor connected to the laptop without any converter.

This seems like a bug based on the resolution of the screen. Any thoughts?

Edit: FYI, the first laptop is a Vista and the new one is Win7.
