Hanging process on exit: Jurassic Primitive War 2 in windowed mode

[mung232-cell]

Hello,

I am experiencing a persistent issue where Jurassic Primitive War 2 fails to terminate correctly when using cnc-ddraw v7.1 on Windows 11.

1. Issue:
   When windowed=true is set, the process stays active in the background after exiting the game from the multiplayer lobby. The game window closes normally, but the process does not terminate. It can be killed immediately via taskkill (without /F), suggesting it is hanging during the shutdown sequence.

2. Details:

• Environment: Windows 11, cnc-ddraw 7.1.
• Reproduction:
  • Launch with windowed=true.
  • Enter the multiplayer lobby.
  • Exit the game.
• Observations:
  • Only occurs in windowed=true (Fullscreen mode works fine).
  • Reproducible with renderer=opengl and renderer=direct3d9.
  • Works normally with renderer=gdi.
  • The issue does not occur when exiting from an active match, only when exiting from the lobby.

Given that it only occurs in windowed mode and is specific to the lobby exit path, it seems there is an issue with the windowed-mode shutdown sequence. Could you please investigate why the process fails to terminate in this specific scenario?

Thank you for your help.
