All the vmware player freezes

Hi,

I'm running vmwplayer in Windows 7, virtualizing a Linux (Ubuntu 10.04) and it goes pretty good, except, some times that the whole virtual machine freezes, the screen goes black and I can't do anything, the icons that shows if it is doing something (like accesing to disk and that kind of stuff) do nothing, like the machine is stopped.

Version of Vmware Player: 5.0.1 build-894247

The machine has enough disk and enough Ram to execute.

If you need more info just ask,

Some solution?

Thanks a lot.
