I have just updated my version of 0.5 running on Ubuntu. When I run the client I get an 'Unable to launch application' window appear. If I ignore it then things appear to be working although I note that there are no longer some options in the menus. Clicking on OK kills the application.

When the error occurs the Java Console shows:

Try cleaning everything out (ant clean; ant) and perhaps get rid of .wonderland-server. I added swing-worker-1.2.jar to the core/, which is a back port of Swing Worker to Java SE 5 and is used by the new Content Brower.

I think Ric Moore had the same issue last week and cleaning everything out solved it.

Correct, I just had to do a complete house cleaning. Question, after a
svn session should we always do ant clean before ant run-server? Ric

I'd recommend it, certainly.

Hello,

You might try going into your java control panel and deleting all temporary Internet files/applications.

Hope this helps,

I have tried that but I still have the same problem. Thanks for the advice anyway.
