On Windows 7 installations, an equivalent behaviour can be observed: the proposed yellow interpolation contour just disappears if the non-containing planes are changed. On Linux, it changes colour to grey.

MITK-1-0 keyword is obsolete, we use Target Milestones in the future.

The bug peter described is a rendering bug. Easy to reproduce with just an image an a corresponding segmentation (or binary image).

Make sure the segmentation is above the image and the image has 100% opacity. Enable the "outline binary" property for the binary image and play with the opacity of the binary image. The contour will be rendered gray. The next update of the rendering pipeline (e.g. clicking in the renderwindow or zooming) will colorize the contour again.

I assume that there is something wrong with the color property in mitkImageVtkMapper2D when the method CreateOutlinePolyData() is involved.

This bug was discovered during testing of 2012-06, updating version. Target milestone is unspecified until general bug review, but feel free to fix it before.
