title: Why do Visual Studio 2012 and ReSharper 7 forget to display Intellisense tooltips?
body: <p>I noticed a strange behaviour in my VS2012 installation. I use VS2012 Pro and ReSharper 7. Intellisense is just not showing code suggestions anymore. I found a few related questions in my research but they always had a slightly different setup going and none could solve my problem:</p>
  
  <p><em><strong>Intellisense is working but, it's not showing the <code>tooltip</code> about selected member functions/Properties anymore.</em></strong></p>
  
  <p>If I take a look at the C# Text Editor Settings in </p>
  
  <pre><code>Tools -&gt; Options -&gt; Text Editor -&gt; C# -&gt; General
  </code></pre>
  
  <p>Most of the times the two necessary boxes <strong>Auto List Members</strong> and <strong>Parameter Information</strong> are selected. However, code suggestions in Intellisense don't work. Sometimes, when I look at the described settings, they are <strong>unselected</strong>.</p>
  
  <p>Selecting them will make code suggestions work as in VS2010 but, only once. When I check the settings afterwards, they are most likely still selected, but code suggestions are not working anymore.</p>
  
  <p>Some people suggested deleting the <code>%AppData%\Roaming\Microsoft\VisualStudio\11.0</code> Folder, which did not work for me. I also tried to reset all changes, which also didn't help at all.</p>
  
  <pre><code>Tools -&gt; Import and Export Settings -&gt; Reset
  </code></pre>
  
  <p>What in the world could make Visual Studio to just <em>forget</em> its settings and trigger such an irrational behavior? </p>
  
  <p><strong>-edit-</strong></p>
  
  <p>I display the code suggestions by pressing <kbd>CTRL</kbd>+<kbd>Alt</kbd>+<kbd>Space</kbd>. However, I have to press that shortcut every time I want to see the suggestions. It has to be possible to automatically display them every time, when possible?</p>
