Okay. I got the message! After mentioning the "Look Mom, No Hands" Mac OS 8 contextual menus utility last time, many many users wrote to remind me that FinderPop does what LMNH can do yet also includes many additional features. And it's free! Based on readers' enthusiastic comments, this program comes highly recommended! FinderPop is now up to version 1.5f7.
Meanwhile, Look Mom, No Hands! is up to version 1.4! It now works correctly with Speed Doubler 8, and fixes some other cosmetic bugs.
