A bug emerged when the "JIM" software was used with SAW. Some of the height values caused a VB overflow error which I have not encountered in other arenas.
It occurs when a number bigger than 127 is multiplied by 256 in the map making routine.
Amazingly this does not happen if you achieve exactly the same result by my first multiplying the value by 16 and then multiplying the result by 16.

So, here is a version of the JIMMSN exe file which does not give the overflow error when map making.
The map it makes is fully compatible with existing versions of JIM, JIMMSN and JIMMSNFL.
