This seems to be a bug in TCustomRibbon.CustomFrameWndProc which recreates the already destroyed form's window handle because it wants to send the CM_CONTROLCHANGE message to DwmDefWindowProc() which can't do anything with it as it is a Delphi "private" message. The only thing that could be done is to detect that there is a DwmCompositionEnabled TRibbon on the form and then intercept all CM_* messages. But this isn't a solution. |

Thank you for the advice. I chose, however, an other approach so that I create and assign the style component in FormCreate and destroy it in FormDestroy. |

|
I do not know exactly the protocol to follow with this issue so I assign it to you again. |
|
|
I cannot do that. Please remove my previous and this note. |
