Parent product is addable to cart - Can I switch this off?

[ruds@multidimensions.co.z]

Hi,
I'm struggling with a problem in the lastest Virtuemart. I'm using Joomla 3.3.3 with Virtuemart 2.9.9b

My client store is on http://www.vegmoflora-accessories.co.za/index.php/our-products/christmas/baubles-hangings

I've setup a parent product SILVER BAUBLES and then the child variants has all the textures and seizes as well as amounts of baubles.
The problem is the parent product should not be addable to the cart as it's just a container product and not an actual product with an actual SKU.
IS there any way for me to make this parent product NOT addable to the cart.
In the backend there's a tickbox to say 'Parent orderable' and I untcked t5his, but it's still possible to buy the parent object on the front end.

Can you please advise. I would really appreacite it.
Thank you!

we are up to 2.9.9f in testing - you should be on at least 2.9.9e  - dozens of bug fixes between b & e
