It's out of beta and it works fine for what I need. Like you there's only one Winders app I need for work but unlike you it's not IE.

I've run IE6 on Crossover for Linux, though, with no problems.

Just tried to snag a copy of IE6 for download at microsoftDOTcom and only IE7 is available and that's only to REAL WINDOWS USERS. (Validation required.)

I can test it if you like if you can get me a copy of the installer.
