There are any number of applications that place an icon in the system tray when they open. These include VMWare Workstation, qt-recordmydesktop, gtk-recordmydesktop, and gapcmon among many others.
None of the ones I have identified here are able to place their icons in the system tray with mga6 running plasma. This makes them unusable; the only way to interact with them typically is through that icon. Well...this is not true of vmware workstation of course, but it is true of the others.
I have hunted and have not identified a setting that would let me do this but it seems to me there must be one someplace - or else there is some important functionality missing in this version of the system tray.
So, how do I get system tray to allow random programs to put an icon in there?
