strange problem

[Thaatu]

Did you install EB with the 0.81a full installer, or..? Anyhow, re-install.

A cursor popping up could be related to an error message thats behind the opening screen. If you run a 2nd program (Internet Explorer for instance), you can try to alt+tab to the other program and then back, to see if you can get to that message (if that is the problem).

But like Thaatu says, reinstall is probably best.
