Works fine for me on this VM. VMWare hasn't provided a graphics card that supports aero yet. So I dunno if that can have any effect. But with aero turned off and VMWare display driver, I can resize the command prompt window just fine.
I'll be installing the RTM sometime later today after I finish backing up everything. It will be running on a Dual Core E4500 2.20Ghz with 3Gb RAM and an ATI Radeon HD4770. ATI has already provided drivers for Windows 7. I'll let you know.
