unity-panel apps running in the background

Question

i noticed that some of my apps are in the background in unity-panel.
the apps are vmware-workstation,jupiter, empathy
this is what i mean

as you can see on the left some of my apps are running but in the background
if i didn't set my unity-panel to see-through i wouldn't have noticed it.
if i restart my laptop and start empathy it doesn't go in the background and also when
i run compiz --replace the apps are back in the foreground this happens a lot when i am working my apps are suddenly in the unity-panel background?

Answer 1

Run this in a Terminal window (Ctrl+Alt+T):

gsettings set com.canonical.Unity.Panel systray-whitelist "['all']"

Answer 2

Well, I copied it from a tutorial on getting VMWare workstation to show up in the panel, but Im guessing Unity has some sort of whitelist blacklist to determine what shows up in the panel, probably to keep a consistent look and feel. After running that command, Chrome and Google Talk showed up as well. I seriously just copied it from another post, and remembered this post and thought it would be helpful.
