Transparent sprite

I want to make a sprite, some text on blue background so that i can chose at render mode solid-no light and in game will apear just the text but i have no luck in doing so..

What i did ...I extracted a .bmp from an already made (and working) sprite and edited it with paint and then made it a .spr with sprwiz, but in game the blue background can be seen...
I tried all the types of sprites in sprwiz (alpha test, index alpha etc) and every time is the same result the blue is rended in game..
Also tried with Easy sprite maker and Sprite Explorer and got the same result...

With additive method i can't do it, because i want the text to be black (or some darker color ) and also withe additive the text becomes transparent and can't be seen (the rest of the area is mostly white..

So what am i doing wrong ?

It is 255 blue... i checked it every time with color picker in paint...

Ok, after some more tries i find out that the picture is scrude up after i save the picture in pain (only modification i made is a dot)...

So what setting should i make when save the picture, or what software to use to edtit that picture, and how exacly..

ya .. i managed to make it with wally (before your post :( ).. Kind of sucks with wally because it has no text tool (or dose it? )... i had to make it wit copy/paste and some tweaking
