MAC startup disc has no more space available for application memory.
I have a new mac, very little memory being used, and only a few programs being run...safari, i-tunes, etc. This error window keeps coming up "Your Mac OS X Start up disc has no more space available for application memory. To aviod problems, quit any applications and close windows you are not using. removing files you are not using from your start up disc will help". This window will come up with only finder and safari running, no other applications running. This has been going on for several weeks now off and on. What is causing this and what can I do?
