Mouseover for Firefox in Applet Mode

When I try to mouseover a node in the Diagram in Applet mode using Firefox, it take a good two seconds for the node to become highlighted. And to select a node from another node take good three seconds.

In IE, it is happening as the mouse moves over.

Is there something that I can do to overcome this issue?

Thank you.

What are you doing to highlight nodes upon mouse-over?

This is all I am doing...
var selectedNodeId; is outside of this function.

function onNodeMouseEnter(sender, e)
{
    var box = e.getNode();
    selectedNodeId = box.getTag();
}

Thanks.

Are you testing with the same diagrams under IE and Firefox? If the diagrams are the same, could you check if IE and Firefox load the same Java versions? From what I can see in my Firefox 3.5, there is a longer delay the first time a JavaScript is called from the applet; perhaps there is some initialization done for the Java to JavaScript intrerop then. After that it runs no slower than in IE.

There also might be some delay when changing the selection if there a lot of items in the diagram. The control spends some time to update the selection lists, raise selected/deselected/clicked events and repaint the view. You might try comparing the refresh speed when the view shows a denser part of the graph with the one when there are fewer visible nodes.

If I run IE and Firefox from Windows, I am getting the same results that you've described.

I was actually running my Firefox from Mac OS (Sorry for leaving that detail out). In here it starts out really slow and then hangs. Therefore, I have no choice but to "force quit" Firefox.

I have Java SE 6 running on my Mac. Do you have a way to test the applet on the MAC on your end?

Thanks.

Are you using the latest JRE update on Mac? Also can you see any messages shown in the Java console? We'll see if we can get one for testing.

Yes. I am using the latest JRE and there is no error shown in the console.

Thank you for your effort into this issue.
