[OpenLayers-Users] Waiting for Vector & WFS loading

[Lee M.]

hello all

since i use vector layers with wfs protocol, there is a little while before
features loaded on the map. So i need to tell user to wait a moment until
they load. 

what best way to do that ?
i found this
http://osgeo-org.1560.n6.nabble.com/Patch-quot-waiting-quot-mouse-cursor-on-WFS-loading-td3961983.html

but not sure if it will work. any body tried it ?
