Thanks very much indeed Richy - excellent information.
It wasn't actually the solution because my tint2rc was already configured the way you suggested, but it certainly showed me the way to go. What I had to do was this:
Autorun tint2 in Fluxbox
Remove fluxbox pannel and systray in ~/.fluxbox/init
Remove systemtray from the list of items in the line session.screen0.toolbar.tools.
On line session.screen0.toolbar.visible: true. Change true to false.
Add (sleep 2s && tint2) & in ~/.fluxbox/startup
Restart Fluxbox.
Taken from a different page of the site you linked to.
Anyway it works beautifully now, so thanks again.
