Anyone have issues with messages out of order on a Mac?

[Chad s]

I have a PC at home, but at my grandparents house where I keep/work on my cars, they have a mac. Running OS 10.4.7, in Safari or Internet Explorer, posts I make on a thread become out of order. So If I post a reply, it doesnt come up on the bottom of the thread, it actually shows up before posts that were made hours or days prior. Any ideas?

Its been like this for a few months now, also, the page number or "view all" links to a thread do not show on the main page of threads.
