pcAnywhere backwards compatibility.
I just learned that 12.5.5 and higher is not backwards compatible. I work for a control systems integrator and have multiple customers that rely on me being able to connect to their systems. And no one is upgrading software unless absolutely necesssary due to economic issues. Now I'm in a major dilemma because I can only connect to half of my customer base depending on which version I have installed. I was recently forced to upgrade to 12.5.5 because of an issue with a patch and windows 7. Then I come to find out about the backwards compatibility issue when dealing with a non-emergency (fortunately) issue.
So I had to back track and install 12.5.0 but leave Liveupdate from 12.5.5 because the Liveupdate 126.96.36.199 will not work properly under Win 7. And you can't directly download Liveupdate 188.8.131.52. So now I have a mix of hacked up software to work under Win 7.
Are you kidding me!!!. Win 7 has been out for how many years and it still can't get done right!
