Never mind about my previous post. I downloaded 3.3.3 and ran the installer and saw the option to upgrade. I did that and verified in the admin panel that 3.3.3 was running. I tried IE 6 again, and it is still doing the same thing.
I have to admit that I don't really understand your other suggestion. Are you saying that I need to verify that the data is getting sent back to the flash movie? Wouldn't the fact that it works in all the other browsers indicate that it works? Even IE 7 works right.
As I mentioned before, I didn't think of this being a web server related problem until it worked correctly on Apache/Mongrel. Could it possibly be a problem with LiteSpeed? If it isn't, I'll pursue other possibilities.
Thanks for the help!
