Thanks for your reply. What’s so odd is that I just went back into my install and am now being prompted to upgrade the Custom Field Template plug-in to version 1.9.7 – looks like I was only running 1.9.6 before, but wasn’t being prompted to update, so I wasn’t aware I wasn’t running the latest version. (Should have double-checked manually, but never thought to.) The changelog for 1.9.7 says “Upgrade of jQuery DatePicker plugin.” so I hold out hope this will fix it. Will report back shortly.
