Hi, your scrollbars are part of control? I mean, are they created via ShowScrollBar(Handle, SB_HORZ, True); ShowScrollBar(Handle, SB_VERT, True); ? You wrote component ECScheme, it is part of ECControls and I didn't use DoMouseWheelxxx methods at all. I use procedure WMHScroll(var Msg: TWMScroll); message WM_HSCROLL; procedure WMVScroll(var Msg: TWMScroll); message WM_VSCROLL; instead to update area and it works well.
