Hello people, I've another problem with my app. Sorry I'm at work and I've no code, but I try to explain in better way. I'm trying to use gluUnproject (I've read the article on NeHe site) so I've my code like this:

main loop
   check MousePos
   Draw
end main loop



in drawing function, I've this stuff:

draw
   clear
   get matrix
   Draw
   write
end draw



Note that draw and write are pushin' and poppin' matrix... the check mouse are the same nehe code. Now, the problem: I don't know if I've to use glOrtho for gluUnproject, but I'm trying to draw a triangle with topper vertex following the cursor; but I've this problem: Image Hosted by ImageShack.us Image Hosted by ImageShack.us When the mouse pointer (red) are in the triangle area (blue) the vertex follow the pointer, but there's a triangle (yellow) that flip on it. If I move the mouse, the blue real triangle became idiot, and doesn't follow my pointer! bof, if someone could help...Tonight I'll post code and snapshot of app!!! Thanks
