So maybe I should spend a few more words on what I mean by "working".

My intention is to hide certain cotrols on screen while a longer running 
ajax call is being executed. After the callback was completed, the 
controls should come back.
When I say it's not working, I mean that the ajax callback is executed, 
even in Chrome, but the hiding of controls doesn't happen.

Once I've got this running reliably on at least four different browsers, 
I really want to use some "please wait" lightbox dialog, but I wanted to 
start simple - and failed...
