K-Meleon Problems with Layout

My WP site has been up for about 2 months now and I’ve received about 5 comments that it is not rendering correctly in the K-Meleon browser. I’m using the Elegant Grunge theme, https://coloradographicdesigner.com . I had not even heard of K-Meleon before, I don’t know if its popular in the US or elsewhere in the world. Anyone know about this issue? I installed K-Meleon on my PC and the blog looks fine.

By the way, the comments were all posted by spammers looking for linkbacks via their comments and it makes me wonder if they are all in one area of the world since they are all similar.
