Showcase module appears on all blog pages even when assigned to just one page

Hi,

I have a problem with the showcase module slideshow in that I can't seem to get it to display on my selected pages only.

I only want it to appear on my main blog frontpage, so selected the Blog menu item from within assignments. Although I have selected this option in my module Assignment, it still appears on lots of other blog pages. How do I get it to display on one page only?

Kind regards

Mel
