A: See if it still happens if you disable the joystick emulation, set joysticktype=none in the [joystick] section of your DOSBox configuration file. Maybe also try unplugging any joystick/gamepad. If you want to use the joystick in the game, try setting timed=false and be sure to calibrate the joystick (both in your OS as well as in the game or the game's setup program).
