cubemapping?

i cant seem to get cubemapping to display properly. it looks as though no matter what size of a texture i use, the cubemap texture size is locked at 1024x1024. i can almost get it to display properly if i raise my resolution up high enough.

i tried v101 and v102 same prob.

here is some visual aid to show ya. I created a texture at 512x512. then created a viewport at 512x512. i copy the viewport to the texture and it leaves gaps. i raised the viewport size to 1024x1024 and the gaps are smaller but it still leaves some black because the areas im copying are off screen when its that big.

OMG!!! im such a TARD!! i have two apps i wrote. one is my editor and another is a map previewer. both of them share the same source code however i had two seperate functions for creating the cube map. Ugh i was editing the wrong one!!
