USB Mouse not working

Hi-
I am running ATV Flash v3.6.4 on my AppleTV and I am having trouble getting a wireless USB mouse to work in any application mode.

My USB keyboard works fine both in Couch Surfer and when launching Firefox.app via nito->Applications, however in both cases I am unable to use my USB mouse to control any functions in either of these applications. The keyboard and mouse are a wireless USB set, so I find it odd one would work and not the other.

Can anybody recommend any troubleshooting steps to try and figure out why my mouse is not working?

Thanks,
Z
