BeautyTips display off screen

I enabled BeautyTips for forms and display the tips on the right hand side of the form, but when a field is really slow to the edge of the browser the tooltip window just displays outside the browser. In many cases this could be solved by just dynamically shrinking the size of the tooltip to fit totally inside the browser window rather than half outside. However if the field was to close maybe it could be smart enough to move to the top or bottom.

I know the qTip2 plugin implements this, I believe they call it collision detection.
