Thanks for the reply Thomas, and thanks for the suggested work-around, Troels.
I am presuming that the bug is in the distance command, rather than in 'create'.  I previously tried to find where this might have crept in (but to be honest, didn't really know what I was looking for!).  I did note that DistSet.c in layer2 had been modified around the time that I saw this issue come in - ie rev 3969 (2 months ago), but I couldn't see anything likely to cause this problem... To be honest I guess it could be something as far back as 3959!
Kind regards
