I haven't the foggiest as to how to implement that...though it sounds 
logical and seems like it would work.

I've never used the trace function, or vlength...you wouldn't happen to have 
a link to an example would you?

This seems like one of those bugs that shouldn't have made it to the final 
version, doesn't it?    >_<
