User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1.19) Gecko/20110420 SeaMonkey/2.0.14 Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.1; ja; rv:1.9.1.19) Gecko/20110420 SeaMonkey/2.0.14 Typing in "seamonkey -help" or "seamonkey -version" in cmd.exe neither starts SeaMonkey nor outputs help or version information. Reproducible: Always Steps to Reproduce: 1. Start "cmd.exe". 2. Add the SeaMonkey installation directory to system path or "cd" to the installation directory. I did the former. 3. Type in "seamonkey -help" or "seamonkey -version". Actual Results: Nothing happens; SeaMonkey doesn't start and there is no screen output. If I start SeaMonkey with an invalid flag, such as "seamonkey -abc", SeaMonkey starts normally, so it seems that SeaMonkey detects the "-help" and "-version" flags. Expected Results: In Linux, the "-help" flag outputs lots of information to the standard output about command-line options whereas the "-version" flag outputs the SeaMonkey version number. Expected result under Windows would be to either start SeaMonkey or output the same information.
