I'm having this really strange bug where my character will essentially get stuck and slowly slide in one direction, and I'm unable to move him. It seems to happen anytime a menu is opened, like dialogue, inventory, and even the pause menu. I think it may have to do with me holding down A, S, W, or D when I open one of those menus, but I'm not sure. The only way that I can fix it, is to restart the game.

I started a new character and got a few hours in with no problems, then this bug started showing up. Has anyone ever experienced it before?

I'm using OBSE v20 with a few mods. I can post the load order if that might help.

Do any of your mods have anything to do withe the main quest? If so you may want to try each mod individually to see which is the affected one.

Do you have a joystick connected? Oblivion has a weirdness like this with joysticks.

Also, I've had menu lockup problems running Streamline.

I do have my 360 controller plugged in, I'll try unplugging it and see if that fixes it
