[ILUG-BOM] Unable to run gOS on VirtualBox

I recently downloaded the 700 mb iso of gOS(www.thinkgos.com) for trying it out.

I am using VirtualBox v3 to run gOS. But it is not booting properly. It loads up , shows option of installing and or just running without install. I choose the latter.

It loads up, the desktop comes up with mouse cursor but then it is all blank. Can't see anything on the Desktop, only the mouse running over a blank screen. I think there might be some problem with Display or resolution, though have provided 700 mb RAM and 64 MB + video memory. Still, no changes in it.

Rest of the OSs run smoothly under virtualized conditions.

My system config is: Ubuntu Studio 9.10 2 GB Ram 128 Graphics Card (Intel 945 series) Lenovo R61 laptop
