I just discovered that the -valign option for buttons mistakes 'top' for 'center' and vise versa:
# this button shows text in the middle $win->AddButton ( -name => 'Button1', -text => 'Hello World', -valign => 'top', ); # this button shows text at the top $win->AddButton ( -name => 'Button2', -text => 'Hello World', -valign => 'center', ); Something to correct in future versions? Roelof
