It may have to do with Window ghosting?
Code below in the dpr turns it off.
procedure DisableProcessWindowsGhosting;
{ Disables the window ghosting feature for the calling graphical user interface
(GUI) process. Window ghosting is a Windows Manager feature that lets the user
minimize, move, or close the main window of an application that is not
responding. Minimum operating systems XP SP1
}
type
TDisableProcessWindowsGhostingProc = procedure; stdcall;
const
sUser32 = 'User32.dll';
var
ModH: HMODULE;
_DisableProcessWindowsGhosting: TDisableProcessWindowsGhostingProc;
begin
ModH := GetModuleHandle(sUser32);
if ModH <> 0 then
begin
@_DisableProcessWindowsGhosting := nil;
@_DisableProcessWindowsGhosting := GetProcAddress(ModH,
'DisableProcessWindowsGhosting');
if Assigned(_DisableProcessWindowsGhosting) then
_DisableProcessWindowsGhosting;
end;
end;
