[MACTCL] different bindings on 10.6 Snow Leopard

[Hans-Christoph S. <ha...@at...>]

In Pd-extended, I'm getting a strange inconsistency with binding to  
key combinations that is only triggered with key bindings that include  
Shift in it.  This happens only on Mac OS X 10.6 using the built-in  
Tcl/Tk.  Mac OS X 10.5 with custom built 8.5.8 works fine, as well as  
Windows and GNU/Linux.  The windows are each a toplevel that has a  
canvas covering the full window, then everything else is drawn onto  
the canvas.  The bindings in question are:

set ::modifier "Mod1"  ;# for x-platform support
set ::altkey "Option"
bind all <$::modifier-Key-a>      {menu_send %W selectall}
bind all <$::modifier-$::altkey-Key-a> {menu_toggle_autopatch}
bind all <$::modifier-Shift-Key-B> {menu_send %W bng}

When I press Cmd-a, menu_send is called once with the canvas id.  Same  
goes for Cmd-Option-a.  But when I press Cmd-Shift-b, menu_send is  
called twice, once for the toplevel and again for the canvas.

There are about 30 $::modifier-Key bindings, 4 $::modifier-$::altkey- 
Key  bindings, and 15 $::modifier-Shift-Key bindings, and this  
behavior is consistent across all of them, it is only the bindings  
with the Shift that get sent twice.

You can see the full code in question here:

Any ideas?
