I came across a problem with Thickbox today. It just wasn’t working properly in IE. Basically I had ajaxed content loading up inside a Thickbox. When the link was clicked, the Thickbox loaded but no content was displayed. All was fine in trusty old Firefox, so what was IE’s problem?

After about an hour of searching through the code and the documentation on the Thickbook site, I was well and truly stumped. On closer inspection to the changelog docs, it clearly states that it has been updated to work with jQuery 1.1.3.1. I was using the most recent version of jQuery 1.2.3!! and assuming that Thickbox would work. I downloaded the appropriate version of jQuery and hey presto!! it worked.

Moral of the story is - don’t ever assume anything - and read the docs!! THOROUGHLY!
