I'm under the impression that there are problems with file locking when QB is run under CrossOver, so that causes problems for multiuser support.
I only want to use QB in single user mode, but it's barely usable (Bronze level support), and it's been that way for the entire life of CrossOver. Either CodeWeavers is unwilling or unable to improve the support for QB, which makes no sense. There is a huge customer demand for QB support, and lack of QB support is keeping a large number of small businesses from converting to Linux.
This has been very frustrating, in the otherwise pleasant experience of using Linux.
I hope CodeWeavers will realize the importance of QuickBooks support, but after all the user voices screaming in unison and the overwhelming silence from CodeWeavers, I'm not optimistic.
Like Ryan and many others, I bought CrossOver only to run QuickBooks. I could not care less if it runs Word, Excel, Internet Explorer, PowerPoint, or any of the other big Windows applications that I long ago replaced with better native Linux applications.
If CodeWeavers is no better at supporting QuickBooks, and refuses to work on improving QB support despite a lot of user requests and monetary pledges, I might as well use Wine instead of buying CrossOver.
