I do too have been experience odd behavior on this site time-to-time. I am leaning towards the site host or the code used on the site because sometimes I click on the Page 1 link and it just does its hour glass thing where if I just click back button on the page or use the backspace button, it moves along just fine. This odd behavior doesn't occur all the time or on any specific page.
This might still be a part browser related since I notice 64-bit IE9 which I don't normally use, seems to move smoother on this site than FF13 does.
:ummm:
