I have a similar problem. When PathExplorer is enabled, right-click is often disabled (it doesn't appear), preventing any number of manual edits. In the past the reason was that nodes or edges had been manually added but the 'not in path' value was empty, so if I then manually entered "false" in any empty box, the dropdown reappeared. Another way of restoring it was to copy the network and paste it into a new, blank network (having already entered 'falses' in the original). Today I dutifully examined all 'in path' cells and found them non-null, but the dropdown was disabled anyhow. I had to disable PathExplorer in AppStore (I'm using 3.10.0), close and save the session, then reopen it. So: will the above jarrr solve my problem, and is it usable on Windows? Thanks.
