Hi, About 4 or 5 days ago I all of a sudden lost my mouse pointer. it just disappears when Battlesector fires up and ONLY BS. nothing else and no other games does this happen. I've tried so many troubleshooting ideas and watched several videos. mouse trails box, mouse driver reinstall, graphics card driver reinstall, resolution change, vsync, you name it ive tried it and to no avail. someone please help. its so ANNOYING you have no idea. every other aspect of the game is just fine as well as every other game i play. this is only happening during Battlesector. only the pointer disappears when the game fires up. menu and gameplay. who has any other ideas i can try out. thanks
