I didn't make it!
So recently, when I open my COD2 Multiplayer game, the game loads but the cursor never transitions into the game cursor. Instead, both the Windows cursor and the game cursor show up on the main screen; I can move the Windows cursor, and the game cursor stays tucked away in the top left hand corner. None of the options respond to the Windows cursor as I drag it over each of them. I can press Tab and toggle through those initial main options, including Quit. But once I hit Quit, a confirmation menu pops up: "yes/no." I can't click on either, and Tab no longer selects either one. Tilde/console still works and I can type /quit. But that's about it. I reinstalled it and it still does this. The only thing I can think of is it might be something in my config file. But that doesn't really make a whole lot of sense that that would be an option you can mess with. It is a config that I've downloaded here: BASHandSlash.com - CoD2 Tweaks: The Danzig Config
But I used that for a few weeks before this started happening, so that doesn't even explain it. Hopefully someone has an idea what this is about. I googled "CoD2 problems" and this was the first link to show up, so hopefully that bodes well for my problem. Thanks for the consideration.
(I googled a variety of mouse problem keywords too, but no one seemed to have had this issue.) :(
