Hello Michael
thanks for all your fine work.
I have run in to something. It concerns the 3DX space mouse.
The controls sometime work and some times I have to start up the V3 and only then after I fudge with the view preferences. And only then do the Space mouse controls kick-in.

Also when I had both V3 and V4 open at the same time the V4 lached onto the moi.ini file that was in my Roaming V3 folder, took on most settings too. Does this sound right to you? This is not a problem for me... i think
