For the third time now I've had to recover my keychain file from time machine after my one of my sticky notes just became blank. The first two times I thought it was due to my own error and I pressed the save dialog before I quit keychain which caused it to be blank but after searching the apple support forums a lot of other people have been experiencing the same issue.
I am sick of the keychain now and I will start to use encrypted dmg files with word documents or text files to store notes. Very disappointed in apple. If I didn't have a time machine backup of the file the note would have been lost, no way to restore. I really hope 10.6.3 fixes this. On a side note hurry up 10.6.3!
