Slider with one-way responsiveness

I have a flex slider on the home page and it adjusts size appropriately as I reduce the window size in my browsers. The problem I’m having (and couldn’t seem to find in the other forum posts) is that the slider does not re-adjust to a larger size when I enlarge the browser window size. I have a couple of sites I’m using Virtue on, and it only happens on one of the sites: eganart.com/2014site

It’s like a chinese finger trap.

The only plugin difference between the two sites is WooCommerce (which I’m afraid to deactivate because I’ve spent HOURS entering products and don’t want to risk anything).

Anybody else run into this???

Insights???
