I was just starting up Logic Pro 9 when my iMac froze and went grey, followed by the lovely "Hey, I need to restart because something went wrong" window. Forgiving, I accepted the restart and allowed it to do so. 5 minutes later, i'm still booting up and show no sign of stopping. After tinkering around, I found the following: Upon startup, Dropbox.app would begin syncing and then a new process called Image Capture Extension would launch. Once this happens, that process would chew up nearly 75% of my RAM, about %25 CPU, and begin writing to my hard drive (no idea what it was writing, no files are showing up). This renders Dropbox useless and I can't seem to start up my Mac without having to spend 10 minutes waiting for the slow machine to allow me to force quit the process. Any ideas on what this is and/or how to fix it?
