When you look at the synergy+ page it does say that it is beta and mostly stable in most cases so all the warnings are there to inform you that it may not work perfectly. I have no problem with them but I do with CentOS 5. When I did the upgrades this morning it upgraded my synergy to synergy+ and caused me all sorts of issue for most of the morning. CentOS on the workstation in question is installed to be a stable system and not a system that installs beta software. If I want cutting and bleeding edge I will play with Fedora.
After reverting everything back to synergy I am back to a productive environment.
