Shrinking Image Gallery On Mouse Hover (just the big image)

Hi there,

I’m trying to make use of the gallery included with Enfold. However whenever I mouse over the mini-previews, the main image starts getting smaller.

Here’s a link to our live website where I’ve applied the gallery (just this one page for now):

I’ve noticed someone else had a similar problem over here:

We’re using the latest version.

Thanks for the great theme – love it.
