Vector View default line weight X6

[Steve C.]

I'm having big time problems getting a vector view elevation to go to layout with the proper line weight. I can not change this crazy default line weight (65534). I have tried everything to change and everything to get the line weights to work out without using the view defaults (which leaves the lines too light). How do I change this default? If I enter a number and tab it goes right back to that number. It's driving me nuts. I've noticed this in another layout but I was able to work around it without any issues. Does anyone know what I can do with this?

I guess I should also mention that this is a plan file and layout I did in X5 on a Windows machine and now I'm running X6 on a Mac.
