I am using iMovie 10.0 on OS X 10.9 Mavericks build 13A603. The computer is a "late 2012" type iMac (2.7 GHz i5, 8 GB RAM).


Even when I close all other tasks, iMovie runs so slowly as to be unusable. Specifically, it seems that every time I run iMovie, it starts some mysterious background tasks that don't show up anywhere (no progress bar, no messages) and slow down the computer to almost a standstill. This happens even when I'm running a very small project in iMovie. When I try to close the program, it asks me: "Are you sure you want to close iMovie library? Tasks that are currently in progress will not be completed."


Please help me get rid of these mystery tasks so that I can finally get my work done. Thanks...

iMac (21.5-inch, Late 2012), OS X Mavericks (10.9)
