I've noticed that when ever I try to let an application be shown on the main page, my comments section gets cut off after the first comment and the remaining comments can't be seen aside from an occasional image. It happens in both IE but not in Firefox.
I notice that this seems to be happening to my friend and I (who used the myspace editor to create our pages) and not to my other friends who have gotten their layouts from other websites. I wish I could help with more.
