Left mouse button will not work to select points in the model screen. It will select a entity that I have drawn in the command line, if I am not in a command but will not function when there is a current command.   I reloaded draftsite 3 times, all the latest version, tried 3 different mice, looked at all the settings I could think of. Finally loaded it onto a old computer I have, and it worked perfect, so I started comparing settings and preferences between the two computers still cant find anything. I do modeling in other cad programs on my newer machine all the time and the mouse works fine. Anyone else ever seen anything like this or is there a hardware problem, I run a wireless mouse mostly, but tried one with a tail, same problem.
