Hi everyone! I noticed since today that the left click of my logitech bluetooth mouse (t630) does not work anymore. E.g. when I click and hold it acts if I would press the left button VERY often. Interestingly, if I switch the secondary and primary click (left/right) with one another, the problem for the simple click function persists. This means I can neither click anything with the bluetooth mouse nor drag and drop (hold). The problem is linked to my user account - the admin account is not affected. I think it started after I connected another logitech USB mouse a couple of days ago. Here are my trouble shooting steps so far (dont wonder, I performed some before realizing the problem is bound to my user account) try to option-shift-click the bluetooth and debug (reset) - no effect I resetted my SMC and PRC - no effect I deleted my bluetooth.plist under /Librarby/Preferences - no effect I booted a linux live CD to check - BT-mouse working as usual I updated the logitech options manager - no effect I deleted the logitech options manager - no effect I connecte a regular USB mouse - works as usual Thus I know, that the problem is bound to my user account bound to bluetooth But I have no idea what to do next. Any hints? Thanks!!
