I had a few macro groups of examples I had downloaded from the forum. They were inactive.
One of them was this:
Which (I think) uses the HScreenArea command in it which is what the log references. Even though they were inactive, I deleted them, restarted Editor and Engine and the problem went away. Not sure why this was happening.
Something very similar happened to me a few months ago with another set of example macros I had downloaded from the forum and the "inactivation doesn’t work, you must delete them" solution did work in that case as well.
