I'm seeing it as well, it comes from TCustomUpDown in the VCL. Basically, the mouse up event gets eaten away by the dialog box and as a result, the buttons still think they are "active". You can see that with their hottrack effect moving with your mouse. For now, I would suggest that no one moves the focus away from the spin edit in the OnChange event. The easiest way to do that is to use PostMessage to trigger the dialog just a bit later on. If anyone finds a solution, please provide a patch. |

I tried to bypass the issue somehow. But only way I found for now is in attached patch. If we do not send UDM_SETPOS message then everything works fine, the only thing that when you click outside after messagebox, then it does not focus control from first click. But not more redundant click handler calls. |
