iPhoto won't "Stop Importing"
QuickTime Pro 7.1.3
OSX 10.4.5
Every time I import anything (photos--Photoshopped or not-- as well as videos) into iPhoto (whether using the File>Import command or dragging & dropping into an album or the Library), iPhoto goes into import mode, the progress bar goes 1/2-way, then indicates "Finishing Import" then never stops its finishing process. Sometimes the stuff I'm importing makes it, sometimes it doesn't. Sometimes the result also is that I lose some of the changes I've made to albums after the import process began because I have to Force Quit in order to get out of iPhoto; that is, when I chose "Quit" from the File menu, it tells me that it can't quit because the import isn't finished.
Any thoughts on what's going on and how I can fix it?
