Again, I don't see any references to the material dialog or a crash in the journal you uploaded.
There is a 4mb limit on uploads to the board, so you pretty much can't upload Revit files at all.
Try posting it somewhere public (Dropbox, or A360) and put a link in your message here if you need to upload a Revit file.
Thanks for looking!
I just created a dropbox account so hopefully this works.
Could an expert reply please?
Same problem is happening even on a new computer that has a different video card and 16 GB RAM!
