How to change mouse appearance over computation

I’m working on some CDF interfaces, and would like to change mouse appearance when perfoming some task.
For example, some code like:

Button["Test Buttom", {changeMouseAppearance["Computing"]; Pause[0.5]; changeMouseAppearance["Standard"]}]

How can I define changeMouseFunc in order to perform that?
I know about MouseAppearance, but I need to change mouse pointer in Time, not in Space.
The code should work on CDF.
Tks in advance

Hi Rodrigo.

When I first read your question, my first idea was to use the java.awt toolkit to change the mouse appearance.
So I started to write some code which uses TimerTask and ActionListeners etc.

Then I read again your question and surprisingly until the end and discovered CDF.

Well, that was the moment where I realized, that I’d completly miss your question…

Unless there is no undocumented feature, I presume this is simply not possible using vanilla CDF.

Hi Stefan,
I have not specified that I’m using Enterprise CDF, maybe your normal Mathematica code could work at this.
