Problems with Safari (includes not being able to re-log in, and spaceing in forums).

Ok so I have two major problems with Safari. The first is that whenever I log in to MyCSULB (university webpage), and then I try to re-log in 5 minutes later, I get a message saying that I can't re-log in for 20 minutes. I forget why, but I can then log into windows vista using bootcamp and use IE to log in again. This problem is exclusive to safari. Does anyone know why and if there is some fix available?

My second major problem involves forums. There are certain forums like the espn message boards that do not work well in Safari. The biggest problem is that I can't space paragraphs properly. For example, if I make a post and make two paragraphs, when I post it looks like one paragraph. The strange part is that if I edit the post, when I edit it looks like two paragraphs as I originally made it. This problem does not occur in windows vista's IE so it is again a safari problem. Does anyone know how to fix this?

I don't like loading my computer with duplicate apps, but right now I'm considering using firefox. I'm hoping there is some fix in safari, a setting perhaps, as I do like safari and it pretty much does whatever I need.
