-have other event commands be processed while message is being shown
**all features are activated by 1 switch**

  BG_MSG_SWITCH_ID = 1
  # This is how many frames will be waited after the message is complete

IF YOU ARE USING YERD MESSAGE SYSTEM THE FEATURES WILL NOT WORK UNLESS YOU USE THIS:
http://www.filefront.com/14137479/BG%20Mes...mpatibility.txt

Customization
You can set which switch enables it and how long the message windows will stay open(after message completes).

Compatibility
This does will work with Woratana's NMS, but it will not have any of NMS's features! However, this must be below the NMS to function properly.

Screenshot
I don't think a screenshot would be useful.
