Hi Mark,
this is a good news :-) , I'm really happy for you.

If you can,  could you post your use case for Pivot (for an embedded app) ?
Could become another user story for Pivot applications in our wiki.

Last, what does it mean "stopped processes from updating anything in the
GUI" (in your code) ?
If you have some hint please tell, it  could be useful even to others.

Thanks for sharing with us your real-world experience with Pivot.

Bye,
Sandro

I will continue to work on it, I think I use far too many<br>

for some efficiencies I can add..<br>

Hi Mark,<br>
<br>
&gt; Is there anyway to make sun.awt.GlobalCursorManager$NativeUpdater.run(=
)<br>
more efficient?<br>
No (sorry), this class is bundled in rt.jar (the main jar for the JRE), so<=
br>
unless you provide a patched JRE I don&#39;t think it&#39;s possible (assum=
ing from<br>
a legal point of view it&#39;s doable, by the license). And we don&#39;t us=
e it<br>
directly of course ...<br>
Note that probably this class interacts with Threads, native (OS<br>
specific) functions and Window Managers and other complex stuff, so anyway<=
br>
it would be an hard task. Its source is not in the usual src.zip (in root o=
f<br>
JDK).<br>
<br>
Here an online version of that class (taken from OpenJDK-7):<br>
