Changing a tile item's ActiveFrameIndex property does not display a specified frame

<para>Hi
There appears somethin not right with setting the "ActiveFrame" or "ActiveFrameIndex".
I have several tiles with Frames on them which are hooked up to a 30 second timer and when the timer is
triggered it starts or stops the animations with the code below (for a nice effect and also so a user can disable anim).
However, I want the Frame to reset to Frame[0] when the animation stop is triggered, but it seems to make no difference
when I assign the ActiveFrame or ActiveFrameIndex to 0 as when it stops it seems dependant on the AnimationInterval
to stop where it feels like…
I believe this code should work, yet it doesnt…
You can see i have "remmed" out some lines which I have tried, but still nothin appears to set the Frame to 0…
Hope this makes sense…

              // showmessage(items[i].Name+#13+items[i].frames[0].name);
              // Items[I].Glyph.Image:= Items[I].Frames[0].Glyph.Image; // try copy image ???
          end;
         end;
         Controller.StopFramesAnimation;
        // LayoutChanged; // /refresh???
       end;
   finally EndUpdate; end;
