[jQuery] SimpleModal error in IE7

[Ricardo Garcia Vega]

Hi! I\'m using your great plugin, but I have a problem with
IE7. The problem comes after closing de simplemodal, I then have to
click twice in the button to open it again, because the first time
there\'s the js error, wich says: \"nodeType\" is null or not a
object...
It only happens with IE...
what can I do?
Thank you very much in advance!
Ricardo
