I'm trying to install GhostBSD 4.0 Beta3 under HyperV 2012R2 and i can't get the mouse working and so i can't get the installer to work

Would need some assistance to get through this, or how i could help with getting it working for others.
edit: ok got it to fast, with alt+tab i got further .. but after installation the "same" problem occurs

Thanx
Adam
