Even with a different xLabel, it still takes awhile. Popup is just not speedy at loading when you have several popups.
...and Popup is the one module that doesn't need any hooking, and does just fine with a simple !reload and !netreloadmodule.

Ideally, being able to destroy the label, reload the module, and then recreate the label should do it. It works for LsBox usually. The trouble there being that !LabelCreate doesn't work.
