I gave this a download and a quick play, it seems very good and a perfect alternative to revising that's for sure! Oddly though I have trouble at the menu screens only, mouse input seems to be slow and jerky making it nigh on impossible to select anything. I assumed this might be a memory issue, but the lowest estimate I get (from dxdiag) says I have 3 Mb of RAM which should be fine, do you have any idea what might be causing the issue, or has it been cropping up anywhere else?
