[Backgroundrb-devel] backgrounDRb problems with results and MiddleMan

[Ezra Zygmuntowicz]

Hey There-

	I think you may be using the old version of the plugin. Make sure  
you install it from here:

http://svn.devjavu.com/backgroundrb

	Try that instead. You will need to remove all traces of the old  
plugin before you install this one.
