Damn small linux in Virtualbox: arrow/cursor/pointer not working?

I have virtualbox up and running on my old Vista machine. I previously had a flawless install with Ububtu as the VM. I tried to add another VM with DSL as the OS. For some reason, the cursor/arrow/pointer thing will not display when I move over the window.

I know it is recording my keystrokes, because of the boot option screen. Maybe DSL does not support my mouse driver??? Any ideas?
