I notice: Every time I have 2 windows open (i.e. one displaying "orders" and one "Trade Now,") I have to refresh the other one after a load or else it won't work. For instance, if I cancel an order in the "orders" page and it reloads, then try to place a trade in "Trade now," it brings me back to the main page. So I have to refresh "trade now" to use it again.
Kind of annoying. I loved Bitfloor's interface, where everything was on the same page, and you didn't need a full page load for anything. BTC-E and Vircurex have nice interfaces in that regard. But CampBX is just slow and annoying.
I still use it as part of my strategy to use 3-4 exchanges simultaneously so that when one goes down, I still have 75% of my trading stash accessible. If 2 go down, I'm still not sitting there staring at the ticker with my jaw dropping, swearing at Support's lame excuses.
