We just posted some changes to the way the mouse scroll wheel works (due to user request) - BW9 only. There is not room in the updater to describe the changes so I will put it here:

1. The scroll wheel messages are now sent to the window under the mouse. Before you had to activate a window by clicking on it before the scroll wheel was functional.
2. In Browse and Search panes the CTRL and SHIFT keys are used to add functionality. In the Browse Window id CTRL is pressed the wheel advances the verse in the hit results window. If CTRL + SHIFT is pressed it advances to the next verse in the version.

Enjoy.
