You might be able to improve performance a little by not using as
much testing. For instance the default color for the member is
rgb(186,188,181), so you can actually get away with setting the
member's color to that on a prepareFrame. Then you're not testing
anything at all with the mouseWithin; you're simply hiliting the
*one* line the user's pointing to.
As a general rule watch out for case statements. They tend to run a
little slower than if...then, as I recall.
Hope this he'ps!
