I downloaded Imovie HD from the apple website over a year ago and have been using it without issue until the last few weeks. For some reason my transitions are not working. When I select one of them there is an error "beep" and they will not add to the project. The odd thing is that sometimes none of the transitions will work and sometimes none of them will work except fade in and wash out. Also odd is that sometimes it is only the transitions that won't work and sometimes the effects won't work either. I have searched around the net and found several topics with suggestions. I tried deleting the preferences for imovie and running repair on the disk utilities. Neither of these things worked. I also saw that I should start a new user account and see if imovie worked under that account. I did this and was able to add transitions and effects just fine under that new user account. So I realize the problem is something to do with my home file. The thing is, anyone have any idea what I can try now? I don't want to have to go under another account every time I want to use Imovie but I don't want to be going through my main account just randomly trashing files hoping it will fix things. Like I said, I already tried deleting the preferences and running the repair on the disk utilities. Any help would be very, very much appreciated.
