Cross Browser Compatibility

For some reason – popmake is being pushed offscreen with browser specific settings.

Is this a known issue? Works well in Chrome but when viewed on Safari the popup is pushed nearly 1000px to the left.

To see in action scroll to bottom and click one of the master/franchisee buttons.
