Strange glitch when entering encryption password on start-up

I setup a Fedora 18 VM tonight to test out the installer. Everything was fine and it is running great except for one small thing:

When I go to enter my password on boot up to access my encrypted partition, it does a return after each keystroke kinda like this..

Please enter passcode for disk VBOX-HARDDISK (luks...)!:*
Please enter passcode for disk VBOX-HARDDISK (luks...)!:**
Please enter passcode for disk VBOX-HARDDISK (luks...)!:***

And so on.

Has anyone else encountered this problem? Could it just be something that happens in VBOX but would be fine on a normal install? I want to install F18 but I am wary until I am sure it will go off smoothly.
