After opening the schematic diagram in the capture, the probability can only click on the selected electrical node, not anything, but the area selection is no problem.
Check the selection Filter is all enabled (right click in blank space and choose Selection Filter).
I tried it. Select Filter only works for area selection, but it doesn't work for click selection. Even if Select Filter disables all elements, it can also click to select all elements. The problem I encountered didn't seem to be caused by select filter.
