I am using Ver 16.3 and just setup a new computer. I have transferred my env file and all user preferences. For some reason I can only cross probe from Allegro to Capture but not back from Capture to Allegro. Others can do both using the same board file and schematic. I have removed all my preferences and just used the defaults and still same result. I have re-installed ver 16.3 and the latest ISR - same result Anyone have this problem and was able to fix it?
