My MBP is only a few months old.. For the past week or so, things are moving very slowly.. For example, if I right click (I'm an ex-Windows user) on a desktop icon and the menu pops up, it takes a second or two for my mouse to catch up as I'm hovering over options.. While I'm typing this message, from time to time, I see no text - but it'll eventually appear on the screen and then follow along just fine.. It happened just now.. I do usually have lots of windows opened.. Chrome, Firefox, Outlook - maybe Dreamweaver or Photoshop.. But I've closed all that down - and I'm still experiencing the issue.. It just happened again.. Any ideas?
