Does anyone else ever encounter their Mac deleting text as they type? I have a track pad and bluetooth keyboard on my Mac desktop, and often, as I am typing, the machine starts deleting what I've typed. In Mail, it deletes messages. It is like the delete key is being held by someone - but it isn't me! I've replaced batteries in the keyboard and trackpad, made sure nothing is touching or near the delete key, nothing seems to work (though curiously, it isn't happening as I type this message - but was a problem all day). Suggestions?
iMac (27-inch Mid 2011), Mac OS X (10.7.5)
