Multiple Clicks
Sometimes when I use my mouse to click on a checkbox or other button, or anywhere else, in Yosemite, it clicks twice instead of once. This has not happened to me in Snow Leopard or Mavericks. I thought it might be an issue with my mouse, but it seems to be a sensitivity issue with the checkboxes, where they will check and then uncheck again after I click on them once, if I click quickly rather than hold the mouse button down. Even if I hold the mouse button down, though, it seems to accidentally toggle the checkboxes twice instead of once.

Called into the Apple Chat. They gave me an 'Exception' (no fee) because of the upgrade issue. Basically they said to clear all wifi info in the 'network' then 'advanced' of System Preferences. Clearing proxies and all references to ANY wifi. I then let it rebuild the connection itself to your Own wifi and all is good. Amazing that it took such an easy step for My situation. I hope this helps others !
