Hi, Reading all this crash and kernel panic posts I really do wonder what I'm doing wrong. I'm using parallels for mac since day one. Never uninstalled a previous version. Always kicked in the newest beta. Never got a single crash. Some beta problems of course - like doing a new install of macfuse 3 since version 4 - which comes with parallels - wont support encfs. This build 5120 is really fast. I was impressesd how fast it did boot compared to the previous beta build. Minimizing windows to the dock is so much mac like - cool thing. I've used linux (suse, fedora, ubuntu) windows (xp and vista) with parallels. The parallels tools support in linux in version 3 comes in handy. All in all no problems. As I said - I wonder.
