Hello, I have been using the 2017 version of draftsight for 8 months. I have always used the default mouse settings.Yesterday for some reason my right click on my mouse stopped bringing up the shortcut menu to choose "enter" etc. I have not changed any settings and I checked and all of the settings appear to be the same as another version that I have. I have tried a different mouse and also checked to see if my mouse is working with other softwares (which it is). I uninstalled the software and re-installed the 2018 version 3 times but still having the same issue. What am I missing here?
