Thanks to memilm who sent me his Fish Picker registry settings I could fix the bug with "Cycle Random Fish". It appeared to cycle only with fish7 set to random! Which of course happened to be the case in my test setup. The bug must have been introduced in version 4.0.3. So everyone please download the now (hopefully) bugfree picker.
