We have just upgraded our system from BW 7.01 to 7.3 SP4. One of the custom web templates in the system uses java script to hide few items on every screen refresh. Post upgrade, this functionality is behaving strangely, as the hidden items automatically get 'un-hidden' on page refresh.
Please let me know if there are any known script issues in web templates in system upgrade scenarios. Any pointers would be appreciated.
