Sprite Automatic Transparency (problem)

Hey all,

I am a user for a time, from Blitz3d (and from the website), but i am starting post in the forum now.

well, i come with a problem:
when i load a sprite it comes with a automatic transparency O.O
i dont know what can be doing it, i use Vista (need to do the Recovery Cd to format and put the XP...), the image is a 24 bits Bmp. i am loading it as a sprite like this: StartWeapon$="images/personageShotgun1.bmp"

Soldier=LoadSprite(StartWeapon$,1)
SpriteViewMode Soldier,1
___________________________

and the textures like this
ShotgunS(1)=LoadTexture("images/personageShotgun1.bmp",1)

used like this
EntityTexture Soldier,ShotgunS(Walkframe)

(walkframe = from the walk loop)

ShotgunS is a 5 elements Array. and the tag 1 can be taked of and the error persists. heres a image from the error (http://img99.imageshack.us/my.php?image=alphabetatestspyfobiajy2.jpg
)

Its from a game project that i am doing. Spyfobia (in english, Spyfoby, or something like that, its because i am Brazilian O.O)

if some one haves a idea about whats happening
thanks

hugs and see ya
