When I use the vSphere Client (against an ESXi 4.1 server) it hangs a lot. It's always at the same place - using the console on a VM. The console stops responding - and a lot of times, the management window stops responding as well. The operating system won't close the window (as the application isn't responding) and requires a force close.

I've had the console refuse to give up the mouse, and have had the console freeze with the cursor in the top left (before any VM software starts, maybe?).

The environment is this: the system is a Dell laptop running Ubuntu 10.10 (Maverick) fully updated with VirtualBox OSE running Windows XP (also fully updated). The vSphere Client is running in the Windows XP VM. Got all that?

How do I keep these hangs from happening? It is very aggravating. I'm still trying just to get the VM loaded with Ubuntu Server...
