I know, bottom right of my screen :P I mean one to replace the windows XP one. As the attached screen dump shows, I've installed objectdock (and very sweet8 it is). But there's no system tray with the free version. And I like having the little icon to say i'm connected to the net/bettery power/avast is alive etc. (I also did the log on screen: http://s3.photobucket.com/albums/y69/hbk619/?action=view&current=logondx.jpg hehe).

Since the system tray is defined in the actual operating system, I do not think it is possible to 'replace' it. Perhaps configure the settings to hide the entire task bar, and then have one of your own implemented..

Yes that would work fine......

just paying for that application (or getting rid of it...) would of course be both easier, cheaper, and more likely to succeed.
