How to capture the System Cursor

Hi all,

I'm developing an app that needs capture the system cursor.

When the mouse pointer leaves the app's forms it is still captured and set by me; I something like:

if(Cursor.Current == Cursors.hand)
{
.........
}
else if(Cursor.Current == Cursors.arrow)
{
.........
}

But It only works with the app's Cursor

Thanks in advance!!
