Here's a rather annoying feature of the new multibit icon definitions.
It seems that it only occurs when using greyscales.

Set the 'monitors' control panel to 256greys, then using the 'color'
control panel change the highlight colour to a colour (rather than
B/W or 'grey').  Everything appears ok - the colour (blue say) is
represented by an equivalent greyscale.  BUT the icl representation
of icons becomes fundamentally unstable from then on - just opening
the 'general' control panel (or anything else that allows you to change
colours in some way) resets the icons on your screen to the standard
1 bit representation.  You can temporarily correct this by reselecting
256 (or 16) greys from 'monitors' - but it just doesn't convince the
computer permanently!

Now I expect you're wondering why one would ever want to have anything
other than 'grey' or B/W highlight on a greyscale monitor?  Suppose
the 'grey' highlight just isn't the shade you want, or you just switched
to greys from a colour monitor.  Anyway, why can't it cope with maintaining
grey representation of colours?
