Sadly,

It would appear that WS4 is simply out of date now and the new owners seem reluctant to update it for operation with DWCS3 - although vague promises have been made it has to be said.

My solution is simply to use the spry menu widget which, although not as pretty as the WS4/MM menus, is very easy to use, much easier to operate and can look quite fine.

I have given up with WS4 (sadly) but do transfer some of the graphics as I've bought them. I manipulate them in Xara.
