Just installed it under Virtualbox 4.0.12 on Win7 and it works well. The avail command mentioned above works fine for me. The boot shell window doesnt shut though, I didnt see that on an earlier version I was playing with? Clicktofront should really be on startup as so handy but I think I remember how to do that myself from distant memory. Only other odd thing in Vbox is you cant shut it down, Aros just says "The selected action is not supported by your system". I havent tried it natively installed on a real PC yet so not sure if thats always the case
keep up the good work
