Tweetie for Mac is needlessly re-writing keychain entries. It appears to do this each time it starts up and logs in. It re-writes the keychain entry for the twitter account password, even though the password has not changed.

Why is this a problem? For people who sync keychains between multiple Macs via Mobile Me, each time Tweetie re-writes a keychain entry, all the other Macs synced under the same Mobile Me account will get a pop up warning that there has been a change to the keychain and asked to decide what to do about it. This has a high annoyance (and user noise, confusing them with a "change" that is not actually a change) factor.

Please only re-write the keychain entry when the password has genuinely changed.
