I don't have this problem with GNAT3.13p/Win98 if I exclude the
-mwindows linker argument. With -mwindows, this does happen. One thing
to remember is that JEWL.IO writes to standard output as well as
creating a dialog box, so unlike true Windows programs, you should not
have the linker argument -mwindows.
