Ok, here we go! 
I've had this problem for ages now, but it's come to the point where I can bear (bare?) it no longer!
Whenever I open iPhoto (latest version - 6.0.6) it runs fine. However after a couple of minutes use it gets ridiculously slow, even loading a menu might take 10 seconds, and ultimately I have to close iPhoto and load it again. Also, whenever I leave iPhoto (ie. I'm running iPhoto...go to use safari, and then come back to iPhoto) I will find it frozen and unusable!
I've tried rebuilding the library, and rebuilding the thumbnails, but neither of these helped.
When I installed the Aperture trial a month or so ago, I imported my iPhoto library and it said that two images could not be loaded because they were bad formats (something of that sort anyway) so perhaps these two files are causing issues...
I'm running on a 867MHz PowerBook (640Mb RAM) and a 2GHz CoreDuo iMac (2Gb RAM) - both have the same issues with iPhoto...
Any ideas?
Thanks
