Thanks, Aleš. Will investigate.
I've been experiencing this same problem with a Free Space page I'm developing. I couldn't figure out what was triggering it, but now I know thanks to Aleš. I frequently work in long sessions on this document, and get the Failed Token message a lot. The Start Date has blanked itself out several times, and I've added it back in several times. Has anyone addressed this bug? What's the status? It's an aggravation.
