In some games (cruise for a corpse, for example), when
the mouse is not caught (ctrl+F10), there is a strange
It is as if the windows cursor(A) acted like an analogic
joystick on the mouse cursor of DOSBox(B). When A is
in the middle of the DosBox window, B is still. If you
move A a little to the left, B starts to go to the left, and
stops only when A goes back to the center of the
window. If you put A a little more to the left, B goes
faster to the left, and so on for the other directions.
I hope you understand what I mean, although the
easiest way to figure it would be to test it by yourself.
If you catch the cursor, there is no problem.
