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? :)

	public boolean close() {
		if (getNestingDepth() <= 0) {
			clearCursors();
			return super.close();
		}
		return false;
	}

	protected void clearCursors() {
		if (cancel != null && !cancel.isDisposed()) {
			cancel.setCursor(null);
		}
		Shell shell = getShell();
		if (shell != null && !shell.isDisposed()) {
