I have been using VMware since it was "free". Now I have the latest, Version 12, and it sucks. (never thought I would say that) But it is NOT as good as the earlier versions. In fact, I may go back to my version 10 so that I can get some reliability. I got this "new" version so that I could install Windows version 10 inside my Linux. I have enjoyed using both OS's for the past 15+ years. Now, I get lockups. I use VMware inside my Linux to run legitimate Windows OS's and it will quite occasionally lock up. Sometimes it will NOT unlock and I will have to not only kill the operation I am performing -but- also kill the OS. Not good. You guys got any fixes???
