<div class="jive-rendered-content"><h2>Known problems in XULRunner 1.9.2</h2><h3>org.mozilla.interfaces.inIFlasher</h3><p>inIFlasher does not work on MacOS. It is needed to show a border around selected elements in VPE.</p><p><strong>Workaround:</strong> To show a border on MacOS the following style is used: "border: 2px solid COLOR_NAME !important". But the workaround has a drawback: if the selected elements has its own border, it is not visible.</p><h3>draggesture event</h3><p>XULRunner does not fire 'draggesture' event on Linux.</p><p><strong>Workaround:</strong> Special button for Drag&Drop actions is used. Instead of listening to the 'draggesture' events, VPE listens to the 'mousedown' event on this button.</p><h3>org.mozilla.interfaces.nsIDragService.invokeDragSession(...)</h3><p>The method invokeDragSession works differently on Windows and Linux. On Windows it exits <strong>after</strong> the session is ended. On Linux it exits <strong>immediately</strong>. The following snippet illustrates this:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><pre class="jive-pre"><code class="jive-code jive-java">document.addEventListener(<font color="red">"dragstart"</font>, <font color="navy"><b>new</b></font> nsIDOMEventListener() <font color="navy">{</font>
