Removing ustation.dgnlib tasks from the taskbar.

Hi all,

I've created some project specific dgnlibs that house particular tasks for each type of project, and that wokrs perfectly.  However I want to disable some of the starndard tasks that get loaded in from the ustation.dgnlib, such as: Surface Modelling, Feature Modelling, Visualization, while keeping the imporatnt onces, like Drawing.  These unused tasks simply take up room within the task bar, and my operators will never use them in their projects.  I've noticed some of the example projects that come with v8i, have this very thing working, but I'm unsure how this is accomplished.
