Hi psychoadept, hiccup
FOUND IT.
It is the addon "desktop lyrics"
Disabled it and the text vanished.
Teach me to read the instructions when I install an add, I don't use LRC files, just assumed the lyric would be taken from the MP3.
Still, the addon lets me apply font type, size and colour to the text.
I now have a large, "always on top", Track and Artist announcement.
Thanks for your help.
Cheers
