>Has anyone figured out how to delete an entry in the MRU list of Databases or Projects on the Start Page of the Task Pane Manager? I tried following through the code, but I admit - it's over my head in just a casual scan. I'm obviously using the Public beta, so this may have an obvious solution in the 'real' version.

Nope, none that I can find. Fish around in HOME(7), any persistent data should be in there. I'll poke around in the code tomorrow.
