Date parameters

I have a report that requests for a date parameter.

When the 'Enter Parmeter Values' window opens, next to the date parameter I see a calendar icon.

Clicking on this icon should open the calendar picker. This works fine on muy development machine.

However on the clients machine it gives a javascript error 'object expected'

Below the field I see a 'business objects' button which also gives a javascript error when pressed.

It's the same issue as reported here [Date Parameter Error;

Any ideas?
