This sounds very much like a bug Guenter Geiger patched a couple weeks back. Miller included the patch in .38-3 and -4, but you can get it in the SF tracker.
devel_0_38 is up to date with pd-0.38-4...
beside that ... i like the idea of the new doc menu, but i'd like to be able to scroll, instead of only seeing the first 30 entries of each directory ...
cheers ... tim
