As of the release of Crossover XI, we're still working to overcome an issue whereby some of the menu items for Crossover and for Windows Applications are missing in KDE, replaced by "question mark pages". There isn't currently fix (note that the menus will still work), but we're working hard to implement a solution for the next update to Crossover XI.
We're rebels. We're misfits. But mostly, we're software liberators. And we're very, very good at what we do. We have to be. Lots of developers work with open source, but only a tiny fraction of those are good enough to get software that was designed for one platform to work on another one. We invented CrossOver software - a unique approach to cross-platform compatibility that does not require dual-boot or another OS license. We launched PortJump to help app and game developers broaden their market beyond Windows® users. And we launched ExecMode to help organizations solve really ugly technical challenges.
