Anyone who has tried to maintain the dynamic nature of the legend item in ArcMap while re-scaling, opening and closing, panning, adding new data, etc. knows what I'm talking about. Stupid thing likes to re-scale at the drop of a hat with no control. This includes font sizes, patch sizes, and spaces between items. Why this was considered a good idea, well, ya got me.
I've asked, posted it in ideas, and I think something might be coming out in 10.1, but in the interim if anyone has a solution, would love to hear it.
