Default Folder X 5.2.1 is available now. It provides a single fix which corrects problems that Default Folder X 5.2 had when setting Spotlight tags and Finder comments specified in a Save As dialog.
The Details: I got a little overzealous with memory cleanup, which resulted in the tag- and comment-setting tasks deleting themselves as soon as they were created. They never got a chance to actually do their jobs – how unfair!
My apologies for the back-to-back updates, and not catching this before release. “Hey, why isn’t this reference marked as ‘weak’ inside this block? I’ll just fix that before I finalize the build – it’s an obvious goof, and what could go wrong?” Right, Jon.
