G'day, I've a favourite mouse. I've serviced it a few times, but it is developing an irritating problem; multiple click events received for a single down press of the most used button. I've already tried reflowing the PCB pads. Speculations are welcome. This might be the next thing I'll try; checking the spring inside the switch cover. http://electronics.stackexchange.com/questions/29955/how-do-i-fix-an-omron-= d2fc-f-7n-microswitch-from-unwanted-clicks/29967 --=20 James Cameron http://quozl.netrek.org/ --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
