  We are using the very old 2.5 version of the spread control. When connected via RDP The mouse wheel no longer works to scroll the grid. Everything else seems to work. Has anyone else had this issue and know a fix or work around?

  Weirdly if we initialize the component outside the RDP the wheel works when you connect through RDP.

  If you initialize the component inside the RDP session then disconnect and work directly on the computer it no longer scrolls.

  Thanks for any help you can give!

  There is an inherent difference in how mouse wheel (WM_MOUSEWHEEL) messages are propagated when an application is started in a local session vs when it is started in a Remote Desktop session.
