[racket-dev] DrRacket - Error using Transpose S-exp

I'm using Arch Linux (64 bit) 2.6.37-ARCH - and the offical current package 
(racket-5.1-1) which includes DrRacket 5.1.

When I use the editor in DrRacket and I press the key combination for 
Transpose-Sexp (c-m-T) the following error is raised:

select in menu%: unimplemented; args were (list (object:wx-menu-bar% ...))
