I have asked about this issue in the VM forum and they have suggested the problem could be to do with the template, and i have been asked to try the Beez template, it isnt installed so im not sure how to test this issue.
I have been so happy with this template and i suspect that the issue is more down to something i have done than anything wrong with the template. I have a test site setup that i can give you access to to test at

Could i ask you to have a look please, this is my post and a link to the VM reply:
If i set the parent product as not orderable in the Custom Fields, which would make sense my "Add to cart" button is replaced by a button that says "Click here for size options" and is not actually clickable (the mouse shows as a red No Entry sign when hovered over it.) see attachement.
Also with it setup like this i get a price in the category view and an option to "Add to Cart" which shouldnt be there at all. The dropdown options work fine in the product flypage.

thanks as always.
