Re: pickdata and select again....

As Mark suggested, maybe you can provide some more details?

I played around with this a little bit with texture mapped polygons.  I even
threw in a semi-transparent polygon to trick it but to no avail. As far as I
can tell pickdata is returning sane results.  How far off are your values
and what are your view settings?  How are you using the pickdata method?
