So, not really payin' much attention, I threw the onload into the first graphic I noticed on the page. Turns out it was the animated one.
Started fillin' in fields on the page and noticed that every once in a while, my cursor would be thrown back into the first field. Being a long day, and lack of sleep kickin' in, I spent about a half hour trying to figure it out, 'till I noticed it was timed perfectly for the beginning of the animation sequence. Moved the onload to a different non-animated graphic and it worked just peachy. :)
Usin' IE6 on Win2k. Is this common behavior amongst the browsers? I mean, when I think about it, it makes sense, and proves to be quite humorous to the unaware. ;)
