OK, video drivers updated and things seem more stable. Thanks for the advice, nruddock. I should have thought - here was me using completely antiquated December'05 video drivers!

Hiya BARcode, I don't regret spending the $1.99 but I might have if the software were essentially too buggy to be used. I have purchased many software packages that did not live up to expectations (or the advertising). It isn't even the $1.99 that is the problem, but rather the time I put into downloading, installing and learning to use it. Fortunately I got much better results this time and Hexagon 2 does look like a very grown up version of Wings3D (which I like) and - at first glance - it sees to be able to handle bigger meshes than Wing3D. As you rightly point out, $1.99 doesn't usually buy very much and the Daz Hex 2 offer seems to be the bargain of the decade. LOL

Now if I can only figure out what it all does.......
