Comment 5 for bug 1852082

I'm not attempting to raise a second problem in this report, but Ian said that a "complex board" could cause the problem with closing PCBNew. What constitutes a "complex board"? Lots of footprints? Lots of vias? Lots of layers? Or maybe a less than straightforward arrangement of zones that is apparently resulting in PCBNew getting bogged down in computation. Otherwise the board is quite simple, with just four layers and not many components.

You may be on the right track with the footprint cache, as I have been editing footprints a lot (to update them with STEP models). I'll check that out. Even so, if this is the issue and PCBNew just needs more time to close, the effect seems pretty extreme. What if I was doing the same with a board with a lot of components? And wouldn't my killing the process corrupt something? I've not seen any corruption.
