Borland Developer Studio 2006 and OpenGL Picking - Graphics

I'm hoping someone here can give some insight into this problem, so
here's some more information on what I've found.

It seems that while in perspective view the function gives wrong
values, but in ortho view the function returns correct values. I have
three windows in the program, one being perspective, the other 2 being
orthographic, and outputting the values in the main window always
gives 2^31 while the orthographic windows seem to give correct values
(at least they are varying dependant on the distance from the camera).

I've also found that if I zoom in on the perspective view (which just
moves the camera position in the direction it is looking, but does not
change the view position) when i get almost to the point where the
near clipping plane passes through the object (meaning that the camera
position is very close to the object, and for this situation the view
position is actually on the object), the picking seems to work, it
gives (im assuming) the somewhat correct minz values. But zoom out
just a tiny bit and it goes back to giving 2^31.

Any ideas?

So, although no one had any ideas for me...

The problem was the Intel Graphic Drivers.

I guess there must be some error for the newest intel mobile drivers
which doesn't allow opengl picking to operate correctly.

* HDMI Audio: 5.10.0.1026

Moving back to version 6.14.10.4020 fixes the problem.

Dear Mr. Junior Developer,
Can u explain me the procedure to work with BDS 2006 IDE using OpenGL to create the graphics or to develop the GUI in BDS 2006 using OpenGL. U can give me any links which may help me in coding in this line or pls mail me at guddappath@bel.co.in
