I use Win 7 and an old Nightly before the new library stuff.
My friend uses Ubuntu, I don't remember the flavor, and got a KiCad update tonight.
I archived a project and sent it to him.
We talked about junction dots; no surprise.
He stated that he deleted a KiCad created junction dot, yet the display did not indicate a disconnect on the trace, nor did file an ERC complaint with running ERC. This seems counter to the testing prior to my previous thread.
Clearly we are using different versions on different OS's, and I can not duplicate in my KiCad version the results of his comments to me.
