RE: No plane graphics in 5.5
Hmmm... I just upgraded from 5.0 to 5.5 on an iMac (16GB RAM (4GB RAM reserved for Windows 7), with an Intel Core i7/2.93Ghz) on Mac OS 10.6 with Parallels Desktop 6 and Windows 7. Everything worked fine on mine, no hiccups. 5.5 on this setup is a bit jerky (the display is not very smooth.)
