I have a strange problem affecting only Mozilla Firefox (latest version). This does nt happen on any other browser.
The problem is that when i insert the date picker and save the page it will display correctly i.e. there will be a button inserted after the field that will correctly call the date picker. However if i then close down Mozilla and re-open the page, the button will not be displayed. In Firebug it is telling me that i have an error in MXW_SmartDate on line 166 of "Kore is not defined".
As i said this does not affect any other browser. I have re-created this on a single page with one field so i know it is not anything to do with any CSS positioning issues or any other code in my form.
