I set the height to 800 and that gave me the OK and Cancel buttons back. Is there anyway you can change the MAX of 100 to say 1000. This would help greatly.
What I am doing is building a product selector. I have approx 1700 products. Each product is broken up into a Family. So, I have the users first select Family to narrow the results presented. That limits the results, but one of the families has over 500 products.
