I see in comments in the source (in 
https://svn.r-project.org/trunk/src/gnuwin32/graphapp/events.c, around 
line 930) that this is a known bug, but I don't know how to fix it.  I'm 
working on an American keyboard, that doesn't have an AltGr key, so it's 
hard to test anything.

One solution would be to add an option to disable handling of shortcut 
keys in menus.  There's probably a better solution, but without being 
able to test it, I don't think I could find it.

Are you familiar enough with Windows internals to work on this and 
submit a patch, or do you know someone who is?
