title: Delphi Help Insight not avalaible if unit does not belong to project?
body: <p>I have a <code>unit</code> with <code>class</code> which is documented by /// tags and it works fine - Help Insight is creating a in-fly desrciption for given method in <code>class</code>.</p>
  
  <p>However, this works fine <strong>only</strong> if given <code>unit</code> belongs to the project. It does not work if the <code>unit</code> is inside a separate package which is installed under Delphi and then used in other project. In such case I have no description window when I hover my mouse over function from documented class.</p>
  
  <p>I've tried put given unit to the search paths and browsing paths of the IDE but it did not help.</p>
  
  <p>Is there any way to overcome this problem?</p>
