OpenGL / VB.NET Alpha Blending Issue

Ok, we have a small and simple component written in VB.NET. It wraps some basic functionality of OpenGL (Tao GL to be specific). There is a form that I use to test functionality of the component. I am having trouble with alpha blending. If you refer to the picture/screen dump, you will see: *Axis *Some numbers in Yellow *Some letters in blue *A pink square. The numbers in yellow are semi-transparent. You can see the green Axis behind the numbers. The "pink" square is actually red, with an alpha value of 0.1. Unfortunately the square isn't actually exhibiting transparent behaviour. You should be able to see the RED axis behind it. Instead the square is turning pink. Here is a list of the functions that are enabled at initialisation: [url removed, login to view](Gl.GL_DEPTH_TEST) [url removed, login to view](Gl.GL_BLEND) [url removed, login to view](Gl.GL_SRC_ALPHA, Gl.GL_ONE_MINUS_SRC_ALPHA) These are not changed anywhere. I need help to get this fixed and also, so that I understand why it didn't work in the first place. If you don't have the Tao opengl dll's you can get them from [url removed, login to view], or you can contact me. - I'll attach them in a bid comment.

## Deliverables

1) Adjusted source code, complete and functioning. (no executable required, I will run in in the [url removed, login to view] 2003 IDE) 3) Exclusive and complete copyrights to all work purchased.
