Display hourglass mouse while starting executable

Hi everybody,

Does anybody know how to change the mouse status to hourglass while starting a .net executable?

I'm working in a c# project and the application takes a few seconds to start, so changing the mouse to a different status will advise the user that something is going on...

I've tried with:
Cursor.Current = Cursors.WaitCursor;
in the main entry point for the application (i.e Program.cs) with no success.

Thanks for your help!
