yes, that's happened to me before..You keep hitting the start key and it reloads a saved game. Its completely irritating, and will drive you insane..
(I assume you hit the windows key, and this happens)..
Every time I hit any Windows Key (left or right) on my keyboard during a campaign game, I get this combination of effects:
1- The "Keyboard Shortcuts" help appears (as if I pressed F1).
2- Sound is muted (CTRL-S)
3- Town and Character labels are turned off (CTRL-T & CTRL-N)
4- The console opens (`)
5- The autosave is reloaded. (CTRL-L)
