Intersection testing on scaled objects

I got a problem with intersection testing on pfNode level
(pfSegsIsectNode): It seems that when testing against nodes which
are parented by a pfDCS which contains a scaling transformation, the
scaling is not processed on the level of Geosets and below. The
effect is that I get intersections only within the extents of the unscaled
object (e.g. in the intersect.c sample: Put a scale into the SCS above
the nodes which form the ramps; the colored ramps are visibly
scaled, but you run thru them on the level of the unscaled
ramps). The effect is the same when intersecting the DCS above the
node rather than the node itself.
Is there a simple workaround for this problem ?
Thanks for any hint.
