Neither is BlendMode(LIGHTBLEND), Is this a driver or OS issue? It's not the card as it works fine under XP.

Is this in GL and DX?

both

Let me show two examples of ALPHABLEND, one works and the other does not.

Not Working, image does not fade in.

Graphics 640,480,0
ima:Timage = LoadImage("bg4.jpg")
Local a:Float
Local b:Float
For a = 0 To 1000
	Cls
	b = a / 1000
	SetBlend(ALPHABLEND)
	SetAlpha(b)
	DrawImage ima,0,0
	Flip
	FlushMem()
Next

This works and shows the image at Alpha 0.5

Graphics 640,480,0

ima:Timage = LoadImage("bg4.jpg")
SetBlend(ALPHABLEND)
SetAlpha(0.5)
DrawImage ima,0,0
Flip

Try in fullscreen ... perhaps Win98 does not support windowed alpha? (or the Win98 driver does not, no idea)

The issue is that one bit of code does the alpha properly and the other does not.

I have actually fixed it now. I have to reset the SetBlend with SetBlend(SOLIDBLEND) and the set it back to ALPHABLEND for it to work. What a Nightmare!
