> This sounds like an April Fools joke, but if it is not, the solution would be to upgrade. Apple no longer supports MacOSX 10.3 and is ending support for 10.4. The reason for us to move to a centralized Ubuntu desktop server is in fact to get out of this Apple imposed 18 months upgrade frenzy, which can quickly become costly in a business environment. The problem here was not to run Wine on Mac OS X, but to run Wine on Ubuntu and connect to this Linux remote desktop from a Mac client via FreeNX. Anyway, thanks for trying to help.
