UI: Problem with modified quotation form when creating new quot

I have written an amendment which adds a new tab (folder) to the standard quotation form to allow the user to populate user defined fields added to the marketing tables.

This works fine when you edit an existing quotation, all the info is saved etc..

But when you go to create a NEW quotation, at the point you select the business partner you are dumped out of Business One with no error msg other than the standard XP 'do you want to send a msg to Microsoft'.

I really can't understand why this is happening and any advice qould be gratefully received!
