I hope I'm posting in the correct section, anyways :

there's a bug - I think - in the "lock" feature

I was using 2 different accounts yesterday. Then, I locked both of them and went out with friends. When I came back to start chatting about our trip, I pressed ( ctrl + space ) to unlock the messenger ( ctrl + space + z) ( ctrl + shift + z ) [tried all of the shortcuts I used for years], nothing happend. After that, I went to the taskbar I found 1 icon, I clicked it twice and the 1 of the accounts showed up only . I tried different methods to bring it but it just won't show up. here's the funny part : I was so frustrated that I started pressing (ctrl + space) rapidly (about 10 times).. then, WLM kept changing status continously .. yeah, that Plus! was not locking WLM ( ) it was changing the status ( busy - online ) and the color my avatar's frame kept changing, too. Finally, I was kicked .. WLM just disappeared and I had to run it again.

WLM 2011

so what do you think? is it a bug?

Locking and unlocking Messenger now both have the same shortcut.  So where your sstatus kept changing, you were probably enabling and disabling the lock.

yeah, I noticed that
but the problem is: it keeps doing that forever untill WLM crashes
