I am currently using a global hotkey combo to lock Snow Leopard whenever away from the desk. Every month or so, on returning I am unable to login, even though the password is correct. The only way to login again, is to restart, after which the same password works fine. I'm wondering if anyone else has seen this behaviour, or has a fix?
Sounds to me like a bug on the machine's OS, when is the last time you reinstalled OSX on that bay... I would just do do simple reinstall, keep the data and flush the settings and start from there... I found that osx (in the latest versions) is alot more dirty then it used to be... Can anyone say iTunes ; )
