I can't get this error in any of my browsers (Chrome, IE9 and Firefox 13) but my friend gets all the colors in Firefox 16, but not in Chrome or IE9. We're both using fairly new Lenovo ThinkPads with Dell Screens. Windows 7.
Here is a screengrab of the gradient color boxes thing: gradient-color-boxes
Here is the original, unfinished game:katapult
Anybody ever come across anything like this?
