MFC- receiving Button-Click-Message failed

Question

I've created a new dialog in my MFC dialog based application. the new dialog contains 5 control buttons.

the following happens and I don't understand why?

1. click on buttonX. (result ok, OnBnClicked message is sent)
2. click on on any place of the application, but not on the dialog.(removing focus from dialog)
3. click again on buttonX (FAILED, OnBnClicked message is NOT sent). but if instead I click on any other button in the dialog (result ok, OnBnClicked message is sent).

and when I do:

1. ...
2. ...
3. click on the dialog area just to set focus on the dialog again
4. click again on buttonX. (result ok, OnBnClicked message is sent)

**I need to do step 3 only if I want to click again on the buttonX! why?? I think it related to SetFocus() but I m not sure how.

the buttons IDC are: IDC_BACK_MEDIA_PRESS_BUTTON 1180 IDC_TOOLS_LEFT_RIGHT 1024 IDC_MEDIA_FOREWARD_BUTTON 1103 IDC_MEDIA_BACKWARD_BUTTON 1104 IDC_TOOLS_HOOD_BUTTON 2346

the dialog properties is:

IDD_TOOLS_DIALOG DIALOGEX 0, 0, 51, 218 STYLE DS_SETFONT | DS_MODALFRAME | DS_FIXEDSYS | WS_POPUP | WS_VISIBLE | WS_CAPTION | WS_SYSMENU CAPTION "Tools" FONT 8, "MS Shell Dlg", 400, 0, 0x1 BEGIN PUSHBUTTON "Media &Foreward",IDC_MEDIA_FOREWARD_BUTTON,7,79,37,36,BS_MULTILINE PUSHBUTTON "&Media &BackWard",IDC_MEDIA_BACKWARD_BUTTON,7,43,37,36,BS_MULTILINE PUSHBUTTON "Back Media Press",IDC_BACK_MEDIA_PRESS_BUTTON,7,127,37,36,BS_MULTILINE | NOT WS_VISIBLE PUSHBUTTON "Hood",IDC_TOOLS_HOOD_BUTTON,7,7,37,36 PUSHBUTTON "Left Right",IDC_TOOLS_LEFT_RIGHT,7,175,37,36 END

I've tried different style like, tool windows, overlapped, popup. it happens in all the cases.

Thanks for the help.

I see that you are filling view with dialog content. Have you put focusing to your dialog? I think this mystic behavior happening only on first mouse click in your dialog (then dialog gets the focus). I'm just guessing :)
