#98 VPolygons move on zoom

[Anonymous]

I'm placing a background image with markers on it onto a View. I then place VPolygons onto the View that match up with these markers (Square markers with VPolygons covering).

I'm using a STD_VIEW and the standard zoom in/out code. Whenever I do zoom out the VPolygons will move, but they will always show up in the same spot whenever I do a max zoom in. Most notably, when zooming out, the sixth mouse scroll zoom out will cause the VPolygon to look like it has shifted 10 or so pixels to the right, but the next mouse scroll zoom will have it back in the correct place.

Can you provide some simple code to reproduce this problem. If difficult, a series of still images (a short video would be even better)?
