No idea - we can not see your computer or read your mind - to get help you have to give us details - see Writing an effective Apple Support Communities question

So far all you have told us is that you have an undisclosed abstract problem on some undisclosed system running undisclosed software

With the amount of information you've provided it's impossible to offer a solution. We can't see your computer so we need to know the details of your problem and setup, i.e.:

• what version of iPhoto are you using?
• what system version are you running?
• what do you see in the iPhoto window when iPhoto opens?
• what fixes have you tried?
• where is your library located?
• did you apply any updates or upgrades just prior to the problem occurring?
• are you running a "managed" or "referenced" library?

• what type of Mac?
• how much free space on your boot drive?

Come on. Give us something to work with here.
