I take it you cant use threads to update graphics using OpenGL ?

DX version shows output

Strict
Import pub.threads
Graphics 800,600	
Local loader:Int = CreateThread(Progress, Null)
Delay(3000)
DetachThread(loader) 
Delay 10
Function Progress:Object(data:Object)
		Cls
		SetColor 255,0,0
		DrawRect 0,0,30,30
		DrawText "TEST", 50, 50
		Flip 
End Function

OpenGl does not

Strict
Import pub.threads
SetGraphicsDriver GLMax2DDriver()
Graphics 800,600	
Local loader:Int = CreateThread(Progress, Null)
Delay(3000)
DetachThread(loader) 
Delay 10
Function Progress:Object(data:Object)
		Cls
		SetColor 255,0,0
		DrawRect 0,0,30,30
		DrawText "TEST", 50, 50
		Flip 
End Function
