Heads up for anyone else running an Intel Mac and using Fusion to run Windows. I made the mistake of picking up v4 yesterday, which proudly notes "90+ New Features" on the box. Well, the only new features I can find are:
-Can no longer autostart a VM when opening the program
-Buggy/broken networking
-New VM preferences window; slow and difficult to use
I'm running OSX 10.6, maybe the improvements are only apparent under 10.7. Either way, be very careful if you're considering a purchase and don't make the same mistake I did.
I've downgraded back to v3.13 and everything works properly.
