does it work as a command-line tool at all? since you're using CGI.pm you can run it from the command line, and just <cntl>+d if it doesn't require input.

i just tried it ( after substituting GDBM_File for MLDBM, since i don't have MLDBM installed ) and it worked w/out a problem from the command line.

now, from a browser - after setting directory permissions so that my webserver can write -

no problem, no error message, nothing.

maybe changing the MLDBM in the tie() to DB_File will do it.
