Simple Mouse Movement

I am an idiot. This must be expressly understood to answer my question with yelling at me. I am using glut to make pong. I want to get the mouse working, so I am trying to get the mouse to move a paddle. (for no real reason I made a block class, as in paddle)

void MouseMove(int x, int y)
{
 	CurrMousePos.x = x;
	CurrMousePos.y = y;
	
	ChangeMouse.x = CurrMousePos.x - PrevMousePos.x;
	ChangeMouse.y = CurrMousePos.y - PrevMousePos.y;
	
	PrevMousePos.x = CurrMousePos.x;
	PrevMousePos.y = CurrMousePos.y;
}
//ChangeMouse, CurrMousePos, and PrevMousePos are simple
//structs with two GLfloats x and y

//I call this each frame
block.UpdatePos(ChangeMouse.y);
//and after drawing the board I do this
glTranslatef(-10.5, CurrMousePos.y, 0.0f);

void CBlock::UpdatePos(GLfloat Mousey)
{
	position += Mousey;
	if(position > maxY)
		position = maxY;
	if(position < minY)
		position = minY;
} 
I know there will probably be a problem with the screen cords not working well with the GL coords (too much movement) but it doesnt move at all unless I resize the window, which makes me think that the problem is not with my movement detection code.

have you tried dividing Mousey by, say, 1000? because your problem could be to do with

	if(position > maxY)		position = maxY;	if(position < minY)		position = minY;
I did try to do that, but I have the same problem. Moving my mouse around on the screen has no effect. Only sometimes when I move it on the title bar, or when I hit the maximize/minimize button will it move.
[EDIT:Deleted answer, I did not read you used Glut and not Win32]

Ghostly yours,Red.
Sounds like you are only getting mouse coordinates when you get a redraw call. Look at where your mouse gets updated.
