Color tag doesn't work when combined with inner bold tag. Tested with Opera & Firefox.
Unfortunately, that's how I've done all my coloring, e.g. director threads.
[color=green][b]Green outer, Bold inner[/b][/color]
Green outer, Bold inner - shows as bold black for me with the new theme.
[b][color=green]Bold outer, Green inner[/color][/b]
Bold outer, Green inner - shows as bold green for me.
The strange thing: Italics, Underline & Strike-through tags are not affected, only the Bold tag.
