I just wanted to document this rather frustrating bug here, so I can look it up later, and hopefully help anyone else who is running into something similar. This bug involves select tags, specifically setting their innerHTML property.
I had a list of options to give to the user, and a select box would work perfectly. Since DOM methods have burned me in the past, I felt innerHTML was the safer route. It appears, that they both have safety curves like a sine and cosine graph.
