function Skip() { if (loDiv) { loDiv.disabled=true } ... }This is an example from one function. What I like about this is that during the processing time of the round trip to the server, which is launched at the end of the Skip() function, I see my entire DIV get greyed out. And, then it reappears updated. So, I like that better than to make it disappear and reappear. The later option is more like a blink. Having it disabled shows that something is in process, additionnally to the browser circling processing object, and in a fraction of a section, an update is being done.
