Hello Michael,

Looks like there may be a bug in the view mesh angle.

Try this:
. start MoI
. create a circle
. planar it to create a disc
. delete the circle, just leaving the disc
. open the options and change the mesh angle to something silly like 100, the display updates to be very coarse.
. change the mesh angle to 10. Display updates again.
. save the file
. close MoI
. open MoI and the file again
. change the mesh angle to 100. Display doesn't update.
