Seems if I have too many signals in my bus I can't see all of them if the height of the bus signal list display exceeds my screen height.. It tries to make another column on the right, but the signal selection labels are blank. If I click one of the blank areas to select a signal it works, I just can't see what I have selected.... odd. This is happening with version 7.2 and 7.1. Will reboot my PC to see if Windows issue..
