I would like to disable page scrolling by pressing mouse middle button in Foxit Reader, as I assign this button for other function (Dictionary search by Lingoes). Lingoes is a pop-up dictionary application that captures texts in any window and does dictionary search. Most other applications (such as Firefox) have ways to disable scrolling by mouse middle button, but I could not find it in Foxit Reader. Whenever I do dictionary search in Foxit Reader window with Lingoes, the PDF page starts to scroll unintentionally. Could Foxit development team tell me how I can work around this issue?

Thanks in advance,
