Hello, I am not sure if it is an issue with the plugin or Google Chrome.
When you activate Suffusion Commerce Pack and run a test under IE and FF everything works well. When you test it on Google Chrome version 21.0.1180.83, there seem to be a minor glitch.
When you go to the Shop page or Products page to view the products, when you move your mouse over the product image; the image shrinks. If you deactivate the plugin and test it again in Google Chrome under products page it works well.
Kind regards and thank you for a great plugin.
