[plt-scheme] Replace & Find in v4.1

Hi,
I run DrScheme, version 4.1 [3m] on Windows XP and wonder where to activate
Replace & Find. The button in the search dialog doesn't react and the menu
items in the edit menu are grey. I looked up Preferences ... and Help Desk
but I couldn't find any hint. What am I missing? If it is not a bug the
switch should be in a more obvious place.
Robert
