Hello.

My intention is not handed down to you well.

Please download this.

Please click Assert-Menu1 several times.

RibbonMenu changes dynamically.

Please click Assert-Menu2 several times next.

RibbonMenu changes dynamically.

However, Assert appears when you operate it several times.

( This phenomenon occurs in for release conspicuously )

I want you to repair this malfunction.

Thank you for the video file. Unfortunately it does not help much. We suspect this issue should be gone if you update the source code for the following method:

void CExtToolControlBar::_UpdateButton( int nIndex )
{
CWnd * pTarget = GetOwner();
            if( pTarget == NULL && ( ! m_bPresubclassDialogMode ) )
                        pTarget = GetParentFrame();
            if( pTarget == NULL )
                        return;
BOOL bDisableIfNoHandler = TRUE;
            if( pTarget->IsKindOf( RUNTIME_CLASS(CFrameWnd) ) )
                        bDisableIfNoHandler = ((CFrameWnd *)pTarget)->m_bAutoMenuEnable;
CExtBarButton * pTBB = _GetButtonPtr( nIndex );
            if( pTBB == NULL )
                        return;
            ASSERT_VALID( pTBB );
            pTBB->OnUpdateCmdUI( pTarget, bDisableIfNoHandler, nIndex );
}

Thank you very much for your advice.

The application works normally.

No. Do we need some more details about what should we do? What, where and how should we click? etc.

Part(1)

Please click a place shown in a figure many times.

A "Debug" version sometimes reappears.

Part(2)

You build application by release.

Please click a place shown in a figure many times.

Assert appears immediately.

Does not the Assert reappear?

Hello.

You are for release, and please test it

"assert" is frequent.

Hello.

Did the bug reappear?

Thanks

We clicked 200 times one button and 200 times another. We didn’t see assertions. Do you have any additional advice on how to reproduce it?
