The paid people to fix their system is their developers... and well..... heh.
btc-e (for example) is super fast (most of the time) and I'm never uncertain what just happened to money after cancelling or filling an order.
I can cancel ~10 orders, and see the money returned, in the time it takes to cancel just one or two on Cryptsy.
I still like Cryptsy, but wish they could make it more responsive and really fix the lag issues.
Try clicking on another tab on your browser when Cryptsy is lagging, and then change back to the tab you were just on. I've been messing with this more today and it works 100% of the time for me (and allows almost instant updates as opposed to waiting a few minutes). Let me know if that works for you?
