CocoStudio_Full_V1.2.0.1.exe issues with Windows OS running in virtualbox

Hello,

I installed CocoStudio_Full_V1.2.0.1.exe on a Windows 7 32bit guest of VirtualBox which runs under Ubuntu 13.10 host.
Shortly after launching CocoStudio desktop link, virtualbox aborts the OS :O!
Has anyone else experience this?

I also tried installing and running in Windows 8.1 32bit guest of virtualbox.
This time, the main UI of CocosBuilder comes up, but upon clicking one of the choices such as UI editor, the program crashes. This time, Windows OS stays up.

Any info appreciated.

Also, look forward to seeing a linux Ubuntu version of CocosStudio.

Cheers
