I am running Ubuntu 10.4 and using Virtualbox very intensively to develop under windows. This is the perfect combination: Virtualbox is excellent and gives great speed, functionality and connectability.
However, I keep getting a keyboard and mouse 'lock-up' and find that I have to power-down my PC in order to get things working again. The strange thing here is that Ubuntu seems to continue working fine: for example audio keeps playing and the system once successfully finished burning a CD even though keyboard and mouse were frozen.
This happens only very sporadically but is a serious problem because I can't have things freezing when I am in the middle of development or am demoing functionality to a client.
At first I thought it was Ubuntu but it only seems to happen when VirtualBox is running so I am wondering whether there is a problem with the keyboard and mouse capture for Virtualbox and that this is causing the problem.
I have de-installed and re-installed Virtualbox but this didn't help.
So does anyone have a idea how I could either fix this problem or how I could get the system to free the keyboard and mouse when I get a lock-up.
That would be a great help.
