I am having trouble using CrossOver on Fedora Core. What is the problem?
The Fedora project is the testbed system for the Red Hat Enterprise Linux distribution. When new features are introduced to this platform it can tend to cause problems with the operation of CrossOver. Fedora Core 9 has a known problem which results in periodic system hangs when running CrossOver or Wine. There will probably be fixed in a future Fedora patch — watch the Fedora websites for updates. On systems that support the ‘NX-bit’, typically AMD x86-64 or Intel EMT64 processors, you may encounter trouble running any CrossOver application.
