The Redesign Bug

Est. Reading Time: 4 minutes

We recently launched the Beacon site with a new design which included a handful of jQuery animation, many of which had replaced the the previous design’s Flash-intensive content. We have recently come across an issue with the jQuery library with some builds of IE7 and IE8 that resulted in an extensive trail of debugging. We concluded that it was a browser issue (even in different OS environments) that was only fixed by re-installing IE. Here I will outline the issue and the debug trail–and hopefully maybe even think up some potential fixes that weren’t explored when testing was originally performed.

The Issue

In IE7 and IE8 we found that refreshing the homepage would crash IE and sometimes handle restoring the tab, other times not.  Microsoft has acknowledged this error in an KB article.

Error message that would periodically show right before the tab recovers.

Details of error.

Advanced error detail screen.

When tab is not recovered, this screen is shown. Had to repeatedly refresh until this error occurs.
