I’m using 2.87. I’ve overrided OnTabWndClickedItemCloseButton(LONG nItemIndex) in my class derived from CExtTabPageContainerFlatWnd.

I think it used to work but after some prof-uis update now it always gives nItemIndex=1 when callback is called. (4 tabs, 1st and last has no close button).

Maybe it was caused by this fix? http://www.prof-uis.com/prof-uis/tech-support/support-forum/cexttabpagecontainerflatwnd-bug-65089.aspx#@lt;/p>

Can you check this please? Thank you.

Thank you for reporting this issue. Please update the source code for the following method:

bool CExtTabWnd::_ProcessMouseClick(
      CPoint point,
      bool bButtonPressed,
      INT nMouseButton, // MK_... values

{
      ASSERT_VALID( this );
      if( GetSafeHwnd() == NULL )
            return false;

      {
