Strange, as apparently some things that worked before do not work 
anymore, and sometimes crash. I will investigate.

By the way, don't expect to put your systrem tray directly inside a 
transaprent window, it won't work. Because "transparent" windows and 
"normal" windows are not compatible on X11. As system tray icons are 
created outside of the system tray (by the application owner), they are 
"normal" windows. So they refuse to be embedded inside a "transparent" 
window.

To workaround that, you can have one transparent form for your panel, 
one normal form for your system tray. The system tray window will have 
no border at all, and will be put on top of the panel form, so that you 
think it is embedded inside. But it won't.

Another point: the "nm-applet" does not use the old system tray icon 
standard, so the Gambas system tray won't see it. Maybe it works if 
there is no application that manages the new standard, like the KDE 
panel. I don't know, I didn't check.
