ok, here's what happened, i was running Avast AV v7, (this had a WebRep toolbar i did not have enabled)
I uninstalled it, and installed v8
after that i noticed that my custom explorer toolbar had vanished, on closer inspection i found that it had been put into a new one called "Avast online Securiity" {angry} i did not ask for this, and the classicshell explorer bar was greyed out, selecting the avast one got me my bar back, but, it was a default off setting, so i would have had to re-select it for every folder manually - screw that
Avast proptly updated and went wibble, so i removed it, but the toolbar was still broken ... now the title has gone !!
so basically i system restored back to the beginning, uninstalled Avast and binned it, far too much bloatware in that, all i wanted was an AV and it fiddled with EVERYTHING !
anyway, what it has left me with is this ........

much amused i am not, i even upgraded to v4.0.0.2 to try and fix the issue, and failed ..... btw, i much preferred the original 4 coloured icon

.... so how the **** do i fix this ?
