I've just uploaded update 114. This changes the artificial intelligence of fighting fish. It should remove the tendency of fish (especially large ones hooked on very light line) to swim to the far shore and thrash against the bank (the "loop bug".) Fish will still tend to move away from the angler in many cases, but will also favor deeper water. A big fish on light line may run, then settle in a deep hole to rest, run again, etc.
Please visit the downloads page (http://www.pishtech.com/downloads.php3) to get the update to version 114 (build 70813.)
