Unable to move files in Finder
Hi,
Starting today, suddenly and surprisingly, I am no longer able to move files via Finder or on my Desktop. When I click on a file, it is selected and the name of the file is high lighted in blue. I can move it around the screen but it is "stuck" to the cursor. When I let go of the mouse button, the file remains stuck to the cursor and sometimes, I can interact with various elements, i.e. buttons, etc. as if the file had never been selected, yet its icon remains attached to the cursor. After a while, the icon will disappear.
I have tried restarting, shutting down and restarting and repairing permissions without success. Any advice would be much appreciated.
Also, looks like auto-correction and spelling is no longer working either as it doesn't recognize misspelled words anymore.
