There is a lot more happening to mousewheel handling, and it's hidden in the LCL. First is that the Mousewheel event is sometimes redirected (at least under Windows). Windows does sent it to the active Window. LCL does redirect it to the Window over which the mouse currently hovers. Have a look at http://bugs.freepascal.org/view.php?id=11768 it gives some hints where the Message goes. I don't remember all of it, and it's Windows only (so you must find the other OS yourself) lcl\interfaces\win32\win32winapi.inc line 180 The Msg send to Synedit is WM_HScroll or something like this. It is also worth checking i f the Msg goes th Synedit or the Scrollbar Good look with this. Hope someone else can shine some more light on it. > Could someone give me a hint where to find and fix this.
