Hi,

Can you find out if this behaviour is due to the high quality bit or 
the preview bit? You can set the high quality bit separately from the 
gui by selecting the "Quality scan" option within the standard option 
screen.

No need really, the code in question hasn't been changed for about 3 
years...
