Thank you so much. My left click often unregisters incorrectly. If not for step 7 and 8, I wouldn't have opened the multiswitch top and clean the contact point. Seems to work perfectly normal now. It'd be a waste to throw away the whole item just because of a tiny defective component. Thanks again for helping me fixed it.
