I run Parallels on a Mac Pro with two 24 " displays. There is a problem since I ran the 10.5.3 update: When running in multiple display mode, Parallels has sporadic hangs with a permanent beachball pointer when I resize a window. Doing the same in single display mode causes no hangs. I use coherence in both modes. The kind of software is not relevant, it happened with CorelDraw X3, MS Access 2000 and Lexware Finanacial Office 2008. BTW: Any hints when _real_ mutli display support will be available ? Thank you very much, Harald
