Conflict between Windows_Command and Dargor's Command Manager

[GideonNorel]

Hey all,

Hoping someone can assist.

Attempting to do a little scripting in RMXP, but having issues with a conflict between, what looks like, Windows_Command and Dargor's Command Manager (I am also using Cogwheel's RTAB 1.16, and the error, so far, only happens at the start of a battle).  Windows_Command returns a TypeError Line 41: cannot convert nil to String.

Here's the Command Manager code, a little modified as to not cause issues with SDK.

# * Instructions
#------------------------------------------------------------------------------
# - To add a command to the command window use:
#               @command_window.add_command("command")
# - To remove a command to the command window use:
#               @command_window.remove_command("command")
# - To rearrange the commands in the command window use:
#               @command_window.set_commands(["cmd1","cmd2","cmd3"...])
# - You can also rearrange the default menu commands using:
#               $game_system.menu_commands = ["cmd1","cmd2","cmd3"...]

If there's anything else, let me know.
