With this new nightly, it seems that my codeblocks.mo file (to obtain menu items in french) is no longer recognized. It was OK with build 3885.
I use Win XP, the nightly and the new wx dll directly downloaded from Berlios.
I tried to delete default.conf to force codeblocks to regenerate it, but it does not solve the problem.
My settings in Environment/View is as previously : with Internationalization checked and the choice (system default).
