    • SWIPELIST, stop moving with zero overlap

      Hello,
      WM_MOTION module continues to run when SWIPELIST reaches its top or bottom position. It seems that SWIPELIST_Callback does not stop motion while handling WM_MOTION message with WM_MOTION_MOVE command.

    • Hello,

      Could you send me a sample to reproduce this behavior and also which emWin version you are using?

      Best regards,
      Florian
