I am trying to use your Plugin and it works great in FF4, Chrome and IE9, but breaks when rendered in IE7/IE8. When you hit the convert button, it displays a 'dim' transparent box over the "SimCurrEx" form with a 'working' spinner. In IE7/IE8, the 'working' box is not sized or the same shape as the "SimCurrEx" form. When it completes, it shifts the rest of the page down and/or grabs the footer div and places it inside the form area.
Any idea how to fix this?
