CiviEvent pop-up message after upgrade to 4.2.7 in Drupal 6

[richieitchy]

I have upgraded my Civi version to 4.2.7 on Drupal 6 after a successful trial run.  I have since come across an annoying little bug.  When I am entering a new event, when I choose a template, a window pops up asking stating that I have unsaved changes, and if I am sure I want to leave this page!

If I select 'Leave this page' the page reloads with the selected template and entered in the 'From Template' dropdown field, and the event type drop down field pre-entered with a option.  I am guessing the reason I am asked if I want to leave the page is due to some Jquery or Ajax script not being able to update the screens fields.

Has any one experienced this, and if so do you have any pointers on how i can stop this occuring.

Thanks

Richie
