Hi, everyone reading this. You may recall, but probably wont, my recent posting about my mouse seeming to be crapping out after too-short a use-life. Well, Im near sure now that the repeated and repeated L-clicks to open incoming mail pieces is due to the ' jittery' quality of a recent Mail update (which offers the 'finger-sweeping' side-to-side) and this 'unstable' quality is why clicking-effeciency has been reduced. Any of you experiencing this? Regardless, can you advise whether I can 'revert' to an older edition of Mail ? And, if so, then how to (and how to save my 'on my mac' folders full of mail) thanks, Chrisman
