I have this problem in the Jolicloud OS. But since it uses UNR underneath (at least apparently), I thought I could get some clues here. I posted this on getsatisfaction under Jolicloud product:

When I am using the notebook-remix interface in Jolicloud, I notice that mouse feedback is off by quite a bit. Application icons (and other links) are highlighted as if the mouse hovered over them, but the mouse pointer is nowhere close to the icon. Icons under the mouse pointer are not highlighted. It is very hard to click and start an application with the mouse.

This only happens in the notebook-remix interface. Everywhere else, the mouse behaves well.

Anyone else seeing this? Any idea for a fix?

I must mention that I am using an unsupported laptop (Sony VAIO VGN-T140P).

I've uploaded a video to YouTube to demonstrate this: http://bit.ly/5oi5Z
