A few posts ago, I mentioned modal pop-ups and using the Lightbox Gone Wild implementation. Everything was going well, until I tested it out in IE6 for compatibility.
Well... to no surprise, there was a slight problem. Every so often when leaving the page, a JavaScript error would appear, complaining that some 'handler' was null or not an object. However, in Firefox, I was not having any problems.
I finally narrowed it down to a line with this call:
Event.observe(window, 'unload', Event.unloadCache, false);
I quickly checked the Prototype API and found out that this call was no longer necessary in version 1.6. I removed this line, and everything is now working fine once again (even on IE6!)
