May be using app_options in xaaes.cnf particularly the option Close last Window Tops Next App for TosWin2 ?There is already an entry for TOSWIN2 there. But the CLWTNA is not set, so it is taking as 0 or default 1 ?May be it is taking 0 as it is no longer default since an entry is there....May be Helmut can explain better.
You can set clwtna=yes for toswin, and hide toswin (Ctrl-Alt-Y) or close all its windows. Or you can top the previous app after the ttp has exited with Ctrl-Alt-Shift-Tab (might be rebound in xa_help if too difficult). -- Helmut Karlowski
