Hey Y'all, I have a GNS 430 W, which performs great, except... I've noticed the "PROC" button no longer functions, it feels like the other buttons, which work fine, but no matter how hard I push; nothing. Does anyone have experience with this issue? I've found a work-around by using the menu on the FPL page. This requires extra selections and keystrokes, but if it's there, I want it to work. Thanks, Jerry
