My system has hung many times while trying to delete nets. Sometimes it even hung while trying to delete traces or components.
I was able to recreate this problem using the 4014BT_5V. I linked the "P" and "O" signals to seperate but merged buses. I copied this circuit 15 times, and merged the buses into one. I found that once I tried to delete a net, the system would just hang. I did not have this problem when I had the 16 components linked to one bus tree using what appears to be an undocumented bus linking scheme.
Is there a problem with the way the system manages nets, or is this a random bug that creeps around? Is this a bus problem, or a net problem? If this cannot be resolved, I will be forced to look at another software packge.
