Problem using V3d_View::WindowFit

I'm in the process of porting our application from 6.2.0 to 6.5.3.
With the old version, I could zoom in on a window using V3d_View::WindowFit. However, since porting to 6.5.3 the zoom does not happen. Any shapes that were shown in the view remain the same size. It does however, have some effect: the view is panned so that an new point is in the center. Also, if I call V3d_View::Scale(), the scale factor is changed by the call. Calling Redraw() has no effect.

Anyone have any ideas what I might be doing wrong? Was there some step that I needed to add for this to work in 6.5.3?

Any help is appreciated!

Hi Eric,

I never had such an effect.

Can you maybe check if the MFC samples work as expected and then see if there are any differences comparing to your "fitting" code?

I still don't know just what is going on, but I have some more information, and can work around it for my uses.

I've found that the problem only occurs if I create an instance of a subclass of AIS_Trihedron and display it in my context. Since the application I'm currently working with does not need the trihedron, my workaround is to simply not create it.
