After reading about the issues reported for full Minitab 14 I tried Student Minitab 14 (current student version) with similar results so I tried full Minitab 12 -- originally for Windows 95 -- and I am glad I did because it does not seem to suffer the problems I had with 14. Projects and graphics can be saved and reopened. Some interaction with the OS requires slightly different strategies than in Wondows but I have been using the software for weeks now. The biggest issue is that the online help is flaky. For example, in Session Command Help I might click on a topic and get the topic one or two positions away on the index. I've been using Minitab for about 30 years so I don't need a lot of help. However, I did get the help file working outside of Minitab tbough I don't remember the details now. You can pick Minitab 12 up for < $100 on eBay and it is vastly easier to use than the Linux default of R (which I also use but do not recommend for beginners).
