Why RefactoringBrowser slows Squeak ?

People:

I cooking the FunSqueak3.10 for show in Smalltalks 2007
http://www.dc.uba.ar/events/smalltalks/2007/

I wish to have RefactoringBrowser and I pick Refactory-md.3846.mcz.

Loads and I have Lint, but the browser seems eat computer and sloooooooows
down.

Any ideas ? Another RB version working in 3.10 ?
