I checked my scripts, and the only one I have doesn't use either of those commands, so I'm fairly sure that's not it. I haven't experienced it again since reporting it, so not sure what was going on. I might have turned it on in the View menu at one point accidentally (not sure), but it struck me as strange how it would turn on again with no intervention after being turned off. Regardless, everything seems to be behaving normally now, thanks for responding.
