Here's an odd one. We have a mixed environment, Mac's and PC's. When I use the script command Send Mail a button on the layout opens a new email message - things work just fine in the PC environment.

However, when a Mac user (using Mac Mail) clicks on the same Send Email button she loses her signature. It shows very briefly when the new email message first opens but then disappears and the signature line selection changes to "none."

Any assistance is greatly appreciated.

I'm having a similar problem, in that my signature tab in Mail reads "None" which is not the default.
