O.P. Bugs when locking
When I lock Messenger, some things happen:
On the convo windows, there's a line right above the writing box, usually stating when the last message was received, or if the contact has changed his name, or status, etc. After unlocking, the last message will be stuck there, until you close and reopen the window.
If the message was "Contact changed his/her name to Contact2", and I lock, that will be the message until I close the window.
Also, I set Plus! not to change the icon for the magnifier icon in the systray. Actually, I'm using Windows 7, so I don't even have the icon. When I lock, the icon shows up.
And it's even more buggy: most of time, the magnifier icon is hidden, "inside" the collapsed list of icons, but once in a while, it shows up next to the clock.
I believe it wasn't supposed to show up at all, but instead, it shows in two different ways.
