In your case, if I read you correctly, you programmatically
highlight/unhighlight features. And I think that's what reveals the
problem.

I can reproduce the problem on
http://openlayers.org/dev/examples/highlight-feature.html

- click on the feature on the right to select it
- in the FireBug console highlight the feature with
map.controls[4].highlight(map.layers[0].features[0])
- then unhighlight it with
map.controls[4].unhighlight(map.layers[0].features[0])
- bug: the feature turns yellow, while it should be blue

To fix this, I think we should move some logic from outFeature to
unhighlight, so this logic applies even when unhighlighting features
programmatically.

Feel free to create a ticket (and possibly a patch) for that.

Thanks,
