I thought I posted this a little while ago but I'm not sure if it was actually posted/visible so I'm trying again.
I do NOT have "lock on startup" enabled.
I have several projects. A few of them are locked with the lock code, whole others (including home) are not.
If I am in one of the locked projects, and then leave or close the app, then when I next open the app, it starts up in that project, not home - which is fine. But because it is a locked project, I am naturally prompted for the lock code.
