Pause key isn't working

[SnakeTheFox]

Just what it says. I've played through maybe 1/3rd of the game thus far, and all of a sudden my pause key isn't working.

I've tried everything from restarting the game, to going into the "KEYS" set file and remapping it to stuff like the spacebar or P, nothing works. I hit "Pause" and it does nothing.

I've tried not having units selected, I've tried having units selected. Makes no difference. I've made new games, loaded old ones, etc. I'm also noticing weird anomalies, like units disappearing when I load an old game. This started happening on the second "Bonus" mission, where you're defending a small village from the Germans as the Russians. I lost towards the final tank rush, reloaded an old save, and one of my anti-tank guns disappeared.

Anyhow I beat that level so that issue isn't a concern anymore, what is really concerning me is my sudden lack of pause functionality. Any help or suggestions would be appreciated.

I'm on the latest patch of the game, if that's any issue.
