As the title suggests....I'm less concerned with new features as there are always work arounds, thats what great about the 3d modeling environment, there is more than one way to skin a cat so to speak.
My main concern with max its how unstable it its, and how it had never been addressed through the annual releases. I have been using 3d max since 8 and I encounter on a daily basis the bug which results in max momentarily hanging then getting the "3d max encountered an error and had to close etc" message. This can be caused by moving a vertex, moving a polygon, undoing several times, or any of a number of standard modeling tasks. Like I mentioned I have used every version off max since 8 and on many different hardware set ups all the way up to 24 gig, hex core machine but it makes no difference.
A little bit of a rant I know, but I am curious to know if anyone else experiences these joys of max :-)
