Back when I used KDE3, I had done *something* to disable the reduplication of 
icons in my systray, but I forgot how it was done, and somehow I lost the 
config file, or whatever it was that I did to suppress it. 

I know it's a trivial complaint, but it's still annoying that when I run most 
apps, duplicate "ghost" icons appear in my system tray, thus taking up yet 
more space in my desktop. I kill them by running the command pkill 
ksystraycmd in a shell, and they go away ... until the next time I start a 
new program, and then it's back. I estimate that it takes about five seconds 
to kill the ghost icons, but those seconds add up, and according to my 
calculations, I have lost about 6 months from my projected lifespan. This is 
time that I'd rather spend doing something else. 

There are some config files which I believed might do the trick: 
/home/<USER>/.kde/share/config/systemtray_panelappletrc
/home/<USER>/.trinity/share/config/systemtray_panelappletrc

In my old KDE3 configuration (or so I *believed* that I remembered), I just 
removed ksystraycmd from this line: 

[HiddenTrayIcons]
Hidden=ksystraycmd

and presto! it was gone. But now it doesn't seem to work. 

I looked for some kind of corresponding config file here: 
/opt/trinity/share/config.kcfg/
but found nothing. (I'm not even sure that the config files in this folder 
perform the same functions as the old config files (which always end in -rc). 

Does anybody have a clue about how to suppress these ghost icons? (And, by 
extension, where are our configuration files, and how do we alter them?)
