Thanks Herbert.
I did as you said and its working fine now. For some reason I had to change the file name from .obj to .st (got that burst of inspiration from SBE at 2am LOL). Don't know if I am going to totally knacker the system by doing that but it seems to be working.
PS I thought the squeak stone age was a bunch cave men trying to make fire at Xerox park by rubbing their mustaches ;-) - have you seen those old videos floating around youtube LOL.
Thanks again
Joe
