Keyboard and mouse input fails after several hour usage

[Takis]

I've been using VirtualBox daily now (for about 10 working days) as my main "workstation" and about once or twice a day, the keyboard and mouse input suddenly fails. Keyboard input fails entirely: I've got a terminal open, and although I am typing no characters appear. The mouse still gives some input, but I cannot use it to actually do a clean shutdown from within the virtual machine, as clicking the "start button" causes it to change appearance but no menu's appear.

So, I've got to reset or shutdown the virtual machine and restart it to be able to continue work.

I'm using Scientific Linux 6.3 (32-bit version) host with an Ubuntu 13.10 (32-bit) guest. The host is using Gnome 2.28.2, the guest is using LXDE (0.5.0?).

I have just updated to 4.3.2 and will report if the issue is still there (although I figure it still will be there as the changelog indicates no changes regarding this).

Please reopen if still relevant with a recent VirtualBox release.
