Sorry to post another bug, I tried to find the problem myself but is definitely a bug I think. I open today a SCH LIB, modified it, and save it with another name. Same with a PCB LIB. But when I tried to associate the PCB LIB with the SCH LIB, I did not find the PCB LIB! In Libraries, Personal, is there, you can open it, edit the PCB LIB, but if you made a search, it is not found. You can copy the name, and paste in the search, I do that many times and in any way possible, and nothing. So when I tried to search that PCB LIB from the SCH LIB, it was not found in search, but I find it in “Select”. No way for “Search” to find that LIB. Later I discovered that the SCH is not found too, I can use it and place it in the schematic selecting it from my Personal list of SCH only if the Search bar in “Search Libraries” is empty. I don’t understand which is the difference between that SCH and PCB LIB and the rest of many that I have done.
