Hi Michael,
many thanks for getting back to me . I have managed to uninstall explorer 9 , which windows doesn't make very easy for you as it doesn't show up in installed programs only updates . This has
caused ati catalyst control centre to now stop working (not too pleased about that to be honest).Is there another solution that doesn't involve unistalling explorer? as I'm tempted to use system restore to get back my ati control panel. My concern with my installation was that fillet that failed in version 2 did work correctly with no issues in v3 beta( but my license is for version 2).So I will have to re do that snowman tutorial to supply you a 3dm as I had undone the fillet and carried on in v3 beta. I will re do this later today. Is there some documentation that explains all of the possible variations when a fillet will fail ? I've had a look at the wiki files and it seems limited in that regard. More documented examples would be great for a noob like me : )

Anyway thanks again
