Submit bug reports to support@slickedit.com...they will always be reviewed and responded to, and fowarded to a developer if necessary.
Be aware that not all slickedit commands on the command line work in the plug-in as they do in the standalone product. Though lots of commands do work, we make no guarantees (see the help on SlickEdit Core Command Line) that they will all work, or that they are all supported. The environments are different, and some commands we actually disable.
That being said, I will probably always try to fix any command that isn't working for you...in this case it looks like there is a problem with the put command in Core. When I get a chance to debug it I will let you know what the deal is.
