I didn't know if anyone tried this yet or not: I read the hint from [I believe] Tom about using Parallels to run C2 on a platform other than Windows. I'm using Virtual Box and XP under Linux Mint and C2 works fine. I haven't completed an exhaustive test on it, but the lag time for running one OS under another isn't a problem so far. I'm going to dabble with WINE shortly and I'll post my results.
The machine running virtual box:
Semron 1300
2 Gigs RAM
NVidia GForce 6150SE on board display adapter.
