im having a program witch includes a 3D picking objects!!
evrey thing seems ok at the first sight. but there is something wierd happening when doing the picking from deffirent quarters of the space!!
for example, if doing the picking from:
the first quarter, the objects will be pushed at normal (the deepest object is the first one).

the secend quarter (to the left). in some cases its act as normal, and in other it makes the opposite (the deepest object is pushed last).
the third quarter , all objects are pushed in the opposite of normal.
the forth square, just like the second one.

what could be the problem?!?!?!?! thats makin me crazy!! i'v been trying to fix it for few days!!
