The guys over at Ajaxian pointed out this neat little tutorial on using Javascript's Canvas.
I wrote a simple script to pop-up a modal-like element when clicking on an “Add” button on the page. I wanted to insert the element into the DOM on first click, and on subsequent clicks, simply reset the form. A bug popped up in IE7 (surprise) that prevented me from checking if I had inserted the element already.
One problem that shows it self a lot, is when you have floated items inside a container, and that container has a background. You will find that the container does a poor job of containing the floated items.
