I am going through an existing schematic replacing components as several that I initially picked are not in stock and I want an accurate BOM. I've noticed that if I replace a part (capacitor, resistor, etc.) with another by using the process of copy, paste to new location, wire connect, delete old then save I end up increasing the memory consumption by 100MB with each step. Within a short time my consumption goes from 626MB to 1.5GB and I start getting Out of Memory errors and can no longer save my work.
Any ideas for workaround? Right now I get through about 5 components and need to shut down and restart PCB123.
