Comment 67 for bug 761409

the updated ppa fixes the problem for me.

there is an issue where a very rapid triple-click on the indicator icon when there is a program maximized sometimes results in the indicator's menu going under the window. (actually, I've only reproduced this with firefox)
I think i also saw it go under the desktop background when there were no programs open.
But it was intermittant and I checked after using ppa-purge to remove the ppa and it still happened, so i think the ppa is fine. its something you would really only notice if you testing out the indicator icons :)
