Cannot enter email address in Iphoto to send photo, the minute I press send the email address blanks out...Help??!!

Question

In Iphoto under sharing, in email, I enter the email address and the minute I click to send the photo, the email address goes blank.  I did set up my account as in my mail account, but the problem seems to be the retention of the address in the address bar going blank.  Help anyone??

Answer 1

This is with iPhoto as the email client, right?  First try the following:
1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your
     User/Home/Library/ Preferences folder.
2 - delete iPhoto's cache file, Cache.db, that is located in your
User/Home/Library/Caches/com.apple.iPhoto folder (Snow Leopard and Earlier).
or with Mt. Lion from the User/Library/Containers/com.apple.iPhoto/
Data/Library/Caches/com.apple.iPhoto folder
3 - launch iPhoto and try again.
NOTE: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding down the Option key when launching iPhoto.  You'll also have to reset the iPhoto's various preferences.
NOTE 2:  In Lion and Mountain Lion the Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and hit the Enter button - 10.7: Un-hide the User Library folder.
If that is  unsuccessful  launch iPhoto with the Option key held down and create a new, test library.  Import some photos and check to see if the same problem persists. If it does try another test: log into another user account on your Mac and try from there.  If it's reacts the same way a reinstall of iPhoto is warranted.  If you can email from the other account your current account is the culprit. 
Post back with the restuls.
