Choice of desktop picture doesn't "stick"
I like to change my desktop picture every few months. I don't use the "Change Pictures" option. One photo is fine at a time.
I haven't been able to get my choice to "stick" after either restart, log out (then log back in), or shutdown and restart. I don't know if any of my Login Items might be interfering--it seems unlikely, and I haven't been able to verify that.
My Login Items include Android File Transfer Agent (hidden), join.me Launcher (hidden), TotalFinder (hidden), AdobeResourceSynchronizer, and EpsonLowInkReminderAgent (hidden).
Any advice would be appreciated. Thank you.
