<h1>AutoFOCUS3 FAQ</h1>
<h2>Installation and Running</h2>
<p>
<ul>
<li> On MacOS
<ul>
<li>You need to accept unknown developer certificates.</li>
<li>You need to move AutoFOCUS3 to your application folder.</li>
<li>If you get an error message on startup which says that AutoFOCUS3 is broken and cannot be started: open a terminal and use the following command:
<ul>
<li>sudo xattr -rd com.apple.quarantine /Applications/AutoFOCUS3.app</li>
<li>As our software is a scientific prototype, our product is not signed which causes a problem due to the security restrictions of MacOS</li>
</ul>
</li>
</ul>
</li>
<li> AF3 does not start
<ul>
<li> Check, that the path to your AF3 (including the AF3 folder itself) does not contain spaces.</li>
<li> If the product does not start because the Java Virtual Machine (JVM) could not be created: Please update your Java installation to Java 11.0.7</li>
</ul>
</li>
<li> Unpacking of AF3 zip file fails with 'Path too long' on Windows
<ul>
<li> Workaround: Unzip into your drive root, e.g., C:/ and give the folder a short name like 'af3'</li>
</ul>
</li>
<li> Menu icons are not displayed on KDE
<ul>
<li> Go to "System settings - Application Style - GNOME Application Style".</li>
<li> Select "Show symbols of GTK buttons".</li>
<li> Select "Show symbols in GTK menus".</li>
</ul>
</li>
</ul>
</p>
<h2>Where can I report bugs or file feature requests?</h2>
<p> Please direct any kind of feedback to our users mailing list (<a href="mailto:af_user@lists.fortiss.org">af_user@lists.fortiss.org</a>). The AutoFOCUS3 teams is happy to support you.
</p>
<h2>How can I connect ports of two components or states of a state automaton?</h2>
<p>Move the cursor close to a port. The cursor will change and you simply have to <i>click and drag</i> to create a connection.
(The old (Version 2.16 and older) <i>ALT+click and drag</i> behavior has been replaced and does not work anymore.)</p>
<h2>How can I add new elements to a diagram?</h2>
<p>
There are three possibilities: either <i>right-click</i> in the model navigator (left side) or in the diagram editor (center) and select the element from the context menu, or drag the element from the model elements view (right side) into the diagram editor.
</p>
