[Therion] colour preview-above broken

Apologies for being so noisy lately. I think the colour preview-above statement might have broken (possibly a few versions ago). The following syntax alternatives all work fine for me. colour preview-below 80 #0 = black 100 = white colour preview-below [80] colour preview-below [80 0 40] #magenta I get an appropriate colour for the passages previewed. However I cannot get the equivalent preview-above statements to have any effect. I always get a thin jet-black outline for the previewed passage. Is it broken, or are my complicated layout files getting the better of me again? Bruce
