I added debug code that does just that.

That version must be pretty old then.  The current code will
'continue' the loop if the enable is not set.  Here's what my VGA
debug code spewed.. Notice that 12.4 is in the tree twice once
disabled (where it is skipped) and then a second time where it gets
picked up.

Perhaps the merge of the static and dynamic trees gets tripped up by
whats in the Config.lb?

Done reading resources.
