5.0 will crash when it can't find the js file. the problem was JFD named the file MsgComposeCommands.js, but changed the Makefile.in to export msgcomposecommands.js I fixed Makefile.in, rebuilt, and it works. marking fixed.

Thanks Seth.

Using 1999042908 build on Linux this is fixed as specified in Summary. Clicing New Message button or Menu item New|Message brings up the Compose window, does not crash at this point. Verified
