Hi,
I've implemented a jface wizard in my swt application. In one page of this wizard a time-consuming operation is monitored by the wizard's progress monitor as follows:

getContainer().run(true, false, new IRunnableWithProgress() {

	@Override
	public void run(IProgressMonitor monitor)
		throws InvocationTargetException, InterruptedException {
monitor.beginTask("", IProgressMonitor.UNKNOWN); 						
      getShell().getDisplay().asyncExec(new Runnable() {

	@Override
	public void run() {
					//my operation			
       }
}
});
monitor.done();
}
});

The problem is that the application becomes not responding a little while after the operation starts. It seems that the fork parameter has no effect, becuase my operation is executed by the UI thread!!!
