Comment 9 for bug 728719

In my case, the systray icons are gone after Expo mode. I use left-lower and right-lower corners of the screen to trigger Expo with the mouse pointer. Currently I have Skype and HPLip. I can see them on Expo mode in the four Desktops, but they go missing after selecting the desktop to use, hence can not get to skype. If I do "unity --replace" they appear, but still might fail anytime. Is this related to this bug?
