I recently reformatted my harddrive. I installed my mouse, a Logitech first wheel mouse. Then I installed the newest from of Yahell Messenger. Now my mouse works with all other applications as far as scrolling. But it doesn't work whenever I open a message window and try to use it to scroll. I have reinstalled both the mouse and Yahell mesenger. What do you think I could do to resolve this minor annoyance?
