The xtra is intended to replace the old BorderPatch which is not working with Director 7 and later.
What's new in version 0.3.1
Now the Border Xtra for MacOS is now free to registered users of Border Xtra for Windows. The Windows serial number is now accepted. BorderReg method is replaced with the register( xtra "Border", # ) method, so the same lingo code for registration can be used on both platforms.
