Hi Bev, thanks for the fast reply!
You are absolutely correct, I am using Media Tags (v.3.2). Thanks for the link to the thread, I am downloading the beta that Mr Menard provided therein. (I’ve already had clients contact us about our site(!)–I have to run his beta, can’t afford to wait for the release. (No disrespect meant toward him!)
Thank you again for your help! Oh, I’ll post again if the beta resolved my issue. (I realize this isn’t your problem, though!)
