Weird, I can't say that sounds familiar -- I honestly hate Photomatix. I think the results it produces are generally too "surrealistic" and or "kitschy." I played with it about five years ago, when I was new to photography, but haven't touched it since.
What image did I say this about? Generally, I tell people to steer clear of Photomatix, and invest in graduated neutral density filters and shoot in RAW, instead.
Thanks for your incredibly kind comments.
