Site lag?

[leeroberts]

For some reason the site lags for me if I open up 2-3 tabs. When it starts lagging, I cannot right click. When I do right click, I see the outline of the box that pops up when you right click come up, but only the outline, it is clear and you can't see any words, but you can still click on the options but you have to guess where the right one is. When this happens it also becomes "laggy" and hard to scroll down.

I am using Firefox with Windows 7. No I don't have a crappy computer. 4 gigs of ram and firefox is the only window I have open. I have never had another this problem with another website. I have ran several forums myself, and used countless others, and this is the first I have seen of this problem.
