Hi Shek_D, Thanks your feedback, Maybe Reallusion Hub is currently launching in a maximized state, your top taskbar is completely covering the Hub's title bar, which is why the resize and close buttons are hidden from view. To quickly resolve this, please try the following workaround: Method : Temporarily move the taskbar 1. Temporarily move your Windows taskbar to the bottom of the screen (Right-click the taskbar > Taskbar settings > Change the Taskbar location on screen to "Bottom"). 2. The top title bar of the Reallusion Hub should now be visible. 3. Click the "Restore Down" button (the square icon next to the 'X') in the top right corner, or simply click and drag the top bar downwards to exit the full-screen mode. 4. You can then resize the window to your liking and move your taskbar back to the top. Best regards, Kayla Reallusion
