When you click on the PayPal Button in v2 of the API, the browser's toolbar etc is also greyed out and not accessible. It is re-enabled when the PayPal process finishes. The actions are the same as if it was a modal popup BUT it applies to the whole browser.
Presumably this is a function built into the PayPal API but I didn't think this was possible but it obviously is.
Anyone know the script to do this?
