Hello,
Sorry for the late respond, I haven't check the notify me and wasn't able to see the update.
The issue is not with VM 3.0.9 but with the latest update VM 3.0.9.4.
I have update the VM 3.0.9 to VM 3.0.9.4 and I notice a change in the layout of the Choose Variant button and also that the button is not click able any more. If you click the image or the title of the product you are moving to the product page as suppose to but the button is dead.
More over I have notice that at the current version of NSP GK5 when you click on the Variant the Url will not rewritten as is supposed to when SEO friendly urls and Rewrite engine mode are on.
Thanks in advance
