Question about rad rails eclipse plugin

lo there all,
anyone using RadRails ? I really dig it, but, one thing irritates me
about it that i cannot seem to make go away.
everything between <% and %> is highlighted with a light grey
background. I know it’s useful, but i don’t like it myself. I have been
all over the preferences, but cannot find a way to turn this off.

anyone have any ideas ?

thanks
