   Texture appears transparent over some things but not others?
  Alright, perhaps someone can help me with this...  I've been wrestling with getting parts of textures to appear completely transparent for some time now, and I'm close, but still not there.  The current problem I'm dealing with is where my 32-bit Targa image appears with transparency over some things, but not others.  Example: I have some debug text at the top left of the screen that shows the coordinates of the mouse cursor.  The text is drawn using some basic Allegro functions that display some rather generic text.  The alpha of the texture works flawlessly when the transparent mouse is moved over this text.  The areas that are supposed to be completely invisible are, and the areas that are merely transparent work correctly.On the other hand, I also drew a white quad on some random point on the screen.  When I move the same mouse texture over this quad, the parts that are supposed to be invisible are black, and the parts that are supposed to be transparent are opaque.  Now why the heck would the transparency work over one thing on the screen but not another?   
  Mayby when you drew the quad you changed renderstates needed for the transparancy of the cursor?GBS   ;  Haha, just solved it... sorry for posting this... but I've literally been trying to solve this for days.  The problem was that the depth test was enabled when the process was done, so the blending wasn't happening.  Instead, the quad was losing the depth test and did not appear.
