Bug 454526

SUMMARY
The alternatives menu doesn't close if you click somewhere else

STEPS TO REPRODUCE
1. Right-click on the start menu or on the hour / date or on the panel
2.  Click on the "Show Alternatives" item
3. Don't click on anything there
4. Click on the desktop

OBSERVED RESULT
In case you change your mind and don't want to switch to an alternative or you want to do it later and not just open something from the desktop, that menu remains open as if it was set to keep open like other windows have.

EXPECTED RESULT
The menu should close itself as you have changed your mind and you want to do do something else or a call call came in and you had to click the answer button or you had to stop the music, etc. 
I don't think this is such an important change that it cannot close until the users chooses something.
BTW, if you have Firefox open for example, then click on the "Show Alternatives" for the start menu or hour /date and then click on Firefox, it will look like it worked because Firefox comes in front.
I noticed only after I minimized Firefox and saw that the alternatives menu is still open, even though I thought id disappeared, which made me open it again multiple times so in the end I had to click on its "Cancel" button 2-3 times
this is how I discovered that you can actually open it multiple time and I don't know what could be useful in that.
Maybe if you have installed an alternative in the meantime, but probably the one that it's already open should be refreshed to show also the newly installed alternative instead of open it again in front of the other one

Not sure if this is really a bug or it works as intended, but to seemed more of a bug or at least a bit strange.
BTW I didn't know in which product should I report this, please move it the the right place if you can or let me know to recreate it somewhere else.
