Demo site works (it's using v1.0.3), but the following test for IE in v1.0.9 fails:
if ( /msie/.test(navigator.userAgent.toLowerCase()) && parseInt(navigator.appVersion,10) <= 6)
because parseInt(navigator.appVersion,10) does not return the version number.
Check out the discussion here http://stackoverflow.com/a/15983064 (their test for IE version won't work for IE11, but that's fine because your plugin only needed to test for older IE).
p.s. Thanks for a great plugin.
