I've got some child dialogs that have single controls on them, in which case vk_tab does not do anything, but the class doesn't return it either.
I made these modifications:
tget.prg

case nKey == VK_TAB .and. GetKeyState( VK_SHIFT )
// AS 23/07/2007 Changes as per 2007/01 FWH
if ::bChange != nil .and. ( ::oGet:Changed .or. ( ::oGet:buffer != nil .and. ::oGet:UnTransform() != ::oGet:Original ) )
// if ::bChange != nil
lAccept = Eval( ::bChange, nKey, nFlags, Self )
if ValType( lAccept ) == "L" .and. lAccept
if Upper( ::oWnd:ClassName() ) == "TCOMBOBOX"
