I follow the instructions from readme.txt , it work but I get this warning:

Strict warning: Only variables should be passed by reference in nodesinblock_nodequeue() (line 302 of C:\xampp\htdocs\drupal-7.12\sites\all\modules\contributed\nodesinblock\nodesinblock.module).

I didn't knew what to do so I can fix it.
