if qwidth > 500 we have small problem
<input type="text" ext:qtitle="Information" ext:qtip=
"This field can contain text!" ext:qwidth="600" />
The background images for QuickTips are not meant for width>500.
If you want to support tips wider than 500px then you will have to edit the image to be wider.

Here's a 700px version. Figured it might save you some Photoshopping time.
Sorry for the .zip file, but the forum wouldn't let me upload this size (resolution) image **shrug**.
