Trashing my preferences???
Corrupt preference files are the cause of many many problems in FCP X. If that is the cause of your problem, then deleting preferences will solve it; otherwise it will at least do no harm.
(In case you don't know, most applications keep your preference settings in little files with .plist extension, in a "Preferences" folder. You usually don't notice and may not care about it unless they become corrupted and then your software may malfunction - as is the case here)
Pref Manager, which I mentioned in the previous post, is a free software which can delete (and optionally backup and restore, in case you want to) these .plist files, without you going to look for them in the Finder.
Deleting preferences does NOT affect your events and projects - it does not touch them. So it is innocuous and usually the first thing to try when FCP X misbehaves.
Jakob's post may well be on to something, especially if the problem happens with some events and not others.
If deleting preferences does not solve the problem, then you may have to delete some folders in the Finder. But let's not  get ahead of ourselves. I suggest you delete preferences and report back.
