I am running VB on Windows 7-64. The version I am currently using is 4.3.20.
I installed 4.3.22 and found I was continually getting disconnected from the server for no apparent reason. I uninstalled VB completely and re-installed 4.3.20 and the problem went away. To confirm the issue I completely uninstalled VB again and tried 4.3.22 and the issue returned. I am thus back on 4.3.20.
Just a gotcha! warning!
