I filed a bug report with Apple - they suggest Total Finder is causing an issue where the right mouse click gets stuck saying “Fetching” and the share button says “No service” - Finder then can not cntrl-click open files nor share. It requires a Mac reboot to resolve (no relaunch or even logout/login fixes it)
This is latest total finder on 10.10.2 Personally I’m not convinced the problem is here but if there is anything in the code ‘injected’ by TF (apple’s words) that could mess Finder up, can someone have a look. It makes Total Finder not useable in Yosemite 
I am trying to follow up with Apple but since there is 3rd party software involved, the bug reports get less priority I think.
thanks
