Sort Criteria and Field section issues

Hi,

I've just installed this module and seem to be having a few issues. Mainly that the 'Sort Criteria' and 'Fields' sections aren't automatically available.
For example I tried adding a new block view and at the end noticed the Sort field was blank saying ''this field currently has no fields defined'', yet there's no button or anything to enable me add a field. When I try savingthe view, it says ''List type requires at least one field'' but still when I check the there is no way of adding a field!!
The same goes for the Sort Criteria section. Although I can save my view without specifying a sort criteria, I really need this section but can not find anyway to activate it.
The result is I've had to keep cloning the default 'Tracker' view, as thats the only view with both the Sort Criteria and Fields sections enabled.
(I use IE7)
Please help... thanks in advance!
