Using Windows 7 RC, downloaded newest version (2.7b18) as well as the beta version of Ultramon (3.0.7) recommended for use with Windows 7.
The dual monitor ES with ultramon does work. However, whenever it comes on, I see the Windows 7 loading cursor (spinning blue circle), and the only way that I can close the screensaver is to press the windows key, right click the icon on the taskbar, and click "close all windows".
My machine is a quad core Intel at 3.5GHz and I have 8GB of RAM... so I don't think this is just an issue of freezing.
Anyone else seeing this problem?
