MOSS Workflows visible from Start Workflow page in WSS

Oct 27, 2008 at 8:39 PM
after installing this feature, I have now noticed that MOSS workflows for Approval, Collect Signatures and Collect Feedback now are visable on the Start Workflow page in a WSS 3.0 instance for any new document library that is created. 

I have confirmed this on a separate WSS instance.   The workflow initiate buttons are visisble but when clicked do not execute the workflow (a good thing).

Is there any way to remove these workflows from the start workflow page?
