Thanks for the suggestions Dan, Jay and Gary. MOUSE_WHEEL_HZ=0 works. It would be nice to use the mouse wheel while split, but not necessary. 73, Don AA5AU -----Original Message----- From: WriteLog [mailto:writelog-bounces at contesting.com] On Behalf Of Don Hill AA5AU Sent: Tuesday, June 03, 2014 8:57 PM To: writelog at contesting.com Subject: [WriteLog] How to disable mouse scroll wheel? Operating W1AW/5 from Louisiana tonight and everytime I hit the scroll wheel on my mouse, it takes my Icom IC-756 PRO III out of SPLIT. It's killing me! Anyway to disable the mouse scroll wheel from doing this? Thanks! 73, Don AA5AU _______________________________________________ WriteLog mailing list WriteLog at contesting.com http://lists.contesting.com/mailman/listinfo/writelog WriteLog on the web: http://www.writelog.com/ ----- No virus found in this message.
