problems of displaying with different machines

Hello, this my first post here…

My problem is:
I have made a program using picking and gluOrtho2D projections. It works fine on my computer but when i run it on some another machines, it doesn’t display the objects that can be picked.
The most strange is that i can pick these objects anyway.
Shortly, it works fine on my computer but on other machines, the objects i can pick are not displayed.

Hi fredoule,
try explicitly setting your render mode (using glRenderMode) to GL_RENDER before you attempt to draw the objects to the screen.

But it displays everything it has to on my computer.
Maybe i got a clue: it seems to be a problem of OS: on win98, it works fine but the problem appears on NT computers
