[plt-scheme] Menu shortcuts and language/keyboard setting on OS X..?

Dear fellow Schemers,

After some forced absence (I had to write a little PhD thesis instead  
of focusing on more important stuff like playing around with PLT  
Scheme), I've come back to notice that modifier keys in menus are now  
available. Great!!

Now I have a weird problem: in 352.5-svn16sep2006 for Intel Macs the  
menu command shortcuts always produce a question mark? in the  
DrScheme editor instead of triggering the menu action if I have set  
the language to Danish---I've got a Danish keyboard. It worked in  
earlier versions of DrScheme and works fine if I set the language to  
US (in the little "flag" menu item in the Finder that can be  
activated in system preferences).

Looks like an encoding issue, but it could also just be a problem  
with my specific system (2Ghz Intel iMac, 2GB RAM, OS X 10.4.7).

Does anyone know what's wrong and how to fix this?

Best regards,

Erich

p.s. Sorry if this is a known issue, I've been very busy recently and  
lost track of what was going on the list.
