cannot open folders on MacBook PRO
On my MacBook Pro I cannot open the folders at all (but Safari and surfing the Net work fine).
When I highlight a folder with my mouse, it jumps to the next folder, then when I highlight that folder it jumps to another folder etc.I hav lost all control of my desktop.
At the same time I cannot put the MacBook to sleep and it no longer puts itself to sleep.I don't know if the two issues are related.MacBook
