title: How can I turn a popup menu invisible?
body: <p>I'm working with Progress release 11.6, appBuilder and procedure editor.</p>
  <p>I'm creating a new window, based on another one. That other window contains a browser, on which a popup menu is attached.<br />
  In my copy I don't want to see the popup menu at this moment (in other words, I'd like to disable it, so that the user does not see it).</p>
  <p>I have tried putting <code>VISIBLE</code> to <code>FALSE</code>, <code>HIDDEN</code> to <code>TRUE</code>, but I'm always getting into problems.</p>
  <p>My code looks as follows, does anybody know how I can turn the popup-menu invisible?</p>
  <pre><code>DEFINE MENU popup-menu-browser
         MENU-ITEM m_Copy LABEL &quot;Copy&quot; ACCELERATOR &quot;CTRL-C&quot;
         MENU-ITEM m_Cut  LABEL &quot;Cut&quot;  ACCELERATOR &quot;CTRL-X&quot;
         ...
  
  browser-object:POPUP-MENU = MENU popup-menu-browser:HANDLE
  
  // not working:
  MENU POPUP-MENU-browser:HIDDEN = TRUE.
  </code></pre>
