Due to the fix done on movement points in the 802 version which meant double clicks would count both as movement points, a bug has developed where if you click at the right time, about half way through the move from one cell to the next, you can get free moves. Currently my record is 30 spaces moved in 1 turn.

All you have to do is time the click right; so the bug must be where the move actually counts the movement point subtracted. By clicking when the unit is right on the edge of the box it counts the unit as being in the new box and doesn't complete the previous move and doesn't subtract the movement point.
