Allow "Minimize" or "Move" NI Package Manager Window during installation

[Tepig]

During installation, we cannot minimize NI Package Manager (NIPM) window even if the window has "_" button at top right of the screen.

I guess this is because the instalaltion window is set to "modal" so, we cannot touch NIPM window.

In addition, we cannot move NIPM window. The window hides my desktop icons so, it's annoying.

As a workaround, you can press [Win] + [D] to minimize everything and see your desktop
