I have the same problem but haven't figured out a fix yet

I have the same problem on windows 10 don't have a fix.

I downloaded it 2nd time then installed and run it again this time no ghost mouse pointer.

I'm having the same problem. -_-

same problem here :(

Same issue guys. Nothing online that talks to this. Other than annoying game is good to go.

GOG's install adds a .sdb Compatibility Fix called "ForceSimpleWindow". This fix worked on earlier versions of Windows, but updates to Windows 10 have broken it for some apps.

Here's how remove this .sdb Compatibility Fix:
Run regedit.exe and navigate to the following registry key- HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Custom\prophecy.exe
Copy just the "{GUID}" part found under the name column in this key.

From a "Run as administator" command prompt run following command> sdbinst -u -g { [guid you got from ..\AppCompatFlags\Custom\prophecy.exe registry key] }

example- sdbinst -u -g {396435cd-b11c-428d-91d1-d62966feb7ba}

You should see the following message if uninstalling the compatibility fix worked "Uninstallation of GOG.com Wing Commander Prophecy complete".
Close command prompt window.

This procedure also works for Wing Commander Secret Ops (secretops.exe).

note: You may have to run prophecy.exe/secretops.exe in the Windows 98/ME compatibilty mode.

Sadly StrayDogs solution does not work as the command prompt does not recognize the {} symbols and you can't paste there.

I now also realise that having the mouse cursor stuck in the middle of your screen makes it so that you can't control your ship with your mouse. I can only control my ship with the arrow keys which is a right pain in the arse.

Have you tried to copy and paste by right-clicking with the mouse? I had the same issue and this solved it.

Yeah I actually did but it didn't work :(

Thanks, that worked nicely!

Quote the GUID. Curly brackets may be interpreted by the shell. Had that problem (though I use powershell, not cmd as my terminal) and quoting resolved it.

Install wing commander Prophecy GOG go to reedit and delete line in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Custom\prophecy.exe it should only be default. next unzip all hires movie zip files into folder named Movies. copy folder into game folder and unzip WCPmoviepatch_testrelease to game folder and also unzip wcpep_release to game folder install OpenGL-WCP_setup and go to game folder and type install
use direct3d and set res and hit install once done install ac3file_0_6b start game.
