Why does Windows XP minimize my full screen window on my second screen?

Question

In the application that I am developing (in Java / swing), I have to show a full screen window on the second screen of the user. I did this using code similar to the one you find below ... Whether as soon as I am in the window opened by the Windows browser, or as soon as I open Windows Explorer (I am using Windows XP), the full window of the window will be reduced to a minimum ...

Do you know any way or workaround to solve this problem, or is there something important that I did not understand with the help of full-screen windows?

Thanks for the help,
