Fixed. It was the UID. Thank you all for the help.
So my wild guess wasn't that wild after all!
Nope, it was right on.
Well I'm glad you got it sorted too.

Years ago, I was running a number of different distros. Some started their UIDs with 500, others with 1000. To keep things simple, more started with 1000, so I chose on the others to use 1000 also. You are allowed to choose any UID you like during the first boot user creation. While I only run PCLinuxOS these days, I still use UID 1000 for my user on all new installations, because all my data, on all partitions, on all hard drives, is owned by 1000:1000, and it's easier to set the desired UID on first boot than to change ownership on 10 years worth of data. Just a thought, to remind you to check for which UID your user is being assigned by default, when you create that user, and let you know you don't have to accept that default if you choose not to.
