MacRumors Forum posting weirdness in Safari

[DTphonehome]

Hey All,
I often have trouble posting with Safari. My initial post is fine (like this one I am posting now), but if I try to "reply" to a thread, after I hit submit, I get a blank screen. Refreshing sends the data again, but I still get the blank screen and nothing posts. I have to switch to FireFox to do my posting.
Anyone else experience this? Is there a fix? I only have this problem in Macrumors. All other forums are fine.

EDIT: Oh, and this is only on threads that I start. Weird!

Try resetting Safari from the Safari menu. :)

Thanks for the advice. Thing is, this is a brand new mac, with a brand new, fresh OS X install. The only bit of Safari I took from my old mac (which also had this problem) was the bookmarks file.

Did you have the same problem on the old Mac?

Yup, identical.
