Bug 51837 [Progress] Bad message in progress dialog
I20040210 I got a bogus message when running a pile of jobs. A progress dialog appeared that read: "The operation cannot proceed because it is blocked by a background" A background what? :)

arrowCursor.dispose();

		super.configureShell(shell);
		shell.setText(JFaceResources.getString("ProgressMonitorDialog.title"));

			waitCursor = new Cursor(shell.getDisplay(), SWT.CURSOR_WAIT);
		shell.setCursor(waitCursor);
