Since version 0.942 XaAES too offers toolbar support as in AES >4.1. However, it does not have the restrictions that all elements have to have TOUCHEXIT status. For XaAES these are quite normal dialogs.
If the toolbar has to be redrawn, it suffices to call WF_TOOLBAR once with the relevant parameters. XaAES recognizes that the toolbar is already present and redraws it.
