Still not solved BUT I figured out what's going on. When I start Opera from desk icon this tip works. But I start Opera from the taskbar & this tip doesn't work. Weird. Anyone figure that out?
First you need to get your nomenclature straight. You have a
kicker panel at the bottom of your desktop. On it you have an
applet named
Taskbar, and another named
System Tray. All three have icons on them, so you need to specify
accurately which you are referring to, as the icons do different things in different places.
Assuming for the moment you are actually referring to the icon on the
kicker panel, it will have a
different command from the one on your desktop, if you
changed the one on the desktop, so there's nothing weird about it. Delete/remove the one on the kicker panel, then drag the one from the desktop onto the panel and choose
Copy Here. Now both will contain the same command, so behave the same.
