[BUG?] Message deletion problem

[Chris Bunch]

When attempting to delete a message I am getting the following error
(although message deletes OK):

Sorry! There was an error: Can¹t evaluate the expression because the name
³2002² hasn¹t been defined.

The error was detected by Frontier 7.0.1 in mainResponder.respond.
