Windows 7 Razer Lachesis Mouse Issues on Windows 7: Driver Compatibility and Fixes Needed

[simpel]

My Razer Lachesis mouse is not working properly under 7 (jumping cursor).

The system cant find the mouse via firmware and also for firmware and mouseware it`s impossible to upgrade..

Anyone knows when razer is releasing new win seven drivers?

I had the same issue when I was on vista x64 I updated to the lastest vista x64 drivers and firmware update on the mouse and not had a problem since.
Currently running the same drivers on windows 7 RC
