In case anybody is interested, Pro/E (an old 2001 version) installed on a new MacBook under WinXP running in "Parallels", the third party virtual machine software. Everything I've tried so far works properly except for the 3 button mouse 3d model rotation. The Parallels software turns "ctrl+any button click" into "ctrl+left button click". As a work around, I used a freeware program called "keytweak" to turn the "apple" key into a "control" key and that fixes the problem.
