How can I make a GUI element move independently of the frame rate?

Question

My Gui is a group which updates all the time from OnGui:

 GUI.BeginGroup (new Rect (current_pos_x,current_pos_y, smartTabBackgroundImage.width, smartTabBackgroundImage.height));

When I move the group I have tried multiplying the current_pos_x by Time.deltaTime in the update loop but this doesnt seem to do anything.

EG..set the speed dep on FPS in the main Update() loop:

 tabSpeed=Time.deltaTime*10;

& now move it...(This is called from OnGui())

 while(current_pos_x<=tabShownPos_x)
     {
         current_pos_x+=tabSpeed;
         yield;
     }

Anyone any ideas?

Why not

 if( current_pos_x<=tabShownPos_x )
     current_pos_x += 10 * Time.deltaTime;

inside the OnGUI(), and kill the need for that coroutine?

Because OnGUI can run multiple times per frame. You generally don't want to try doing movement inside OnGUI.
