bbText doen't work

heres the code

BBTexture u;
BBModel s;

s = bbCreateSprite();
u = bbCreateTexture(200,20);
bbSetBuffer(bbTextureBuffer(u));
bbCls();
bbText(1,1,"Loading",1,1);
bbSetBuffer(bbBackBuffer());

bbEntityTexture(s, u);

the string doesn't appear... Why?

1. Your texture must be power of 2. otherwise they get stretched
2. Drawing onto buffers does not work on any hardware ... but disabling TFormFilter tends to help.

bbTexture(200, 20, 0); .... you could've told me it was the argument!
