the cell data sub will be called every time the cell needs to be 
rendered (because it needs to know what data to render), and i believe 
the cells are rendered when the mouse moves over their rows.  if your 
cell data sub does anything intensive, that can cause performance 
problems.  not sure why it would cause flicker, unless you were doing 
gui work in the sub.
