title: Omnet++ IDE keeps freezing when starting own project
body: <p>when I start my own project in the workspace folder:</p>
  
  <pre><code>/home/schmidtd/workspace
  </code></pre>
  
  <p>the IDE immediately is freezing and I can't use it aynmore. I'm working on Ubuntu and its just getting gray after I start my project.</p>
  
  <p>BUT!!</p>
  
  <p>if I start the  IDE with the preinstalled workspace folder:</p>
  
  <pre><code>/home/schmidtd/omnetpp-4.6/samples
  </code></pre>
  
  <p>it works perfectly. Does anyone had the same problem or has a solution for me?</p>
  
  <p>Thanks</p>
