I have the latest version of SL, Mac, and have tried installing QS multiple times and using Apple Forums, have avoided certain plug ins like Apple Airport etc and have deleted the Plugins Folder in my home directory and started again.
However, I still have problems activating QS. When I press COMMAND + SPACE, the insert field does NOT find anything. Neither a document, nor photo nor an App. I used to love QS working on Leopard, but now can't even get it running on SL. Any help/suggestions greatly appreciated. Thanks R
