It would be primarily byte size (loading time) not processor

performance.

If it is true.

At the moment I am going to be more neutral on use of which is best for

a simple rectangle hit area and say either is OK.

Which is better will have to wait until I figure out which of my tests

is giving the correct answers. One shows the symbol technique is better

and the other vice-versa. I think I know what the diff is but have to

claify it and the diff is small either way so even if you have hundreds

of buttons this is still relatively minor. But, it is at the top of my

Byte analysis when I get to spend some time on it. I hate it when the

numbers don't add up :-)


One point is you always want to use symbols for first level graphics if

they are used more than once, but this is not always true about nested

graphics. In other words symbols make out of symbols is not always the

right course.

To be honest at the moment I don't always know when one is better than

the other and I often try both especially when we are trying to squeeze

bytes or performance.
