Actually, commenting one line of the method is a nicer fix. I think it keeps

"Make the receiver's height and width be harmonious with those of the

| container ht nav |
container _ self pasteUpMorph ifNil: [self currentWorld].
 ht := (nav := ActiveWorld findA: SugarNavTab)
[nav height]
*"referent height:  (container height - ht)."*
 referent width: (referent width min: container width - self width).
referent top: container top + ht

I don't know why that line is so slow, though.
Cheers. Richo
