This problem has been sending me up the wall for *months*!! I've had dozens of email dialogues with Kensington support with no outcome. It's totally ruined the Mac experience for me! It happened on my old 8500 with OS 9.1. And, when I got this new G4 a month ago, it also happened on both of the installed OSs. I've been considering suicide ;-) Then this from Larry Duffy: >set Chording Speed to Fast. *BINGO*!! Unbelievable! Honestly, that little titbit has been worth hundreds of pounds to me. Many, many thanks, Larry. I should have come here a long time ago. Sorry for my gushing, but I'm over the moon! Roy P
