Overlap checking

Dear all,

I wrote this email to both ROOT and AliROOT mailing lists, because I don't know at what level the problem could be. I have implemented something with TGeo, and when I try to draw it with the OpenGL viewer, I get a picture like the one I attaches (it is a detail of the whole).
As it is quite evident, there IS an overlap, because I didn't compute correctly the translation of the blue box in the picture, and then it is not placed exactly in the hole I prepared for it, and something "enters" the yellow volume before it. Nevertheless, when I run the "CheckOverlaps" method of gGeoManager, it tells me that there are NO overlaps.
What's wrong in my test macro? I attached it also to the email, but the geometry object I created is not in CVS, so you can just look at the code and tell me if there is something wrong in how I use the geometry objects.

Thanks for any help

Best regards,

       Alberto
