Hello, We just develop a dictionary application and get the problem when running with Jaws. Our application runs very smooth and well without Jaws but with Jaws, it responses very slowly. Can you tell me how to completely make Jaws not processing any things in a certain application? Already use the sleep mode, Pass Key Through but still cannot solve the problem. Your help would be very highly appreciated and thankful. We use the Combo Box standard control of windows. In that control there are 2 controls, one Edit and one listbox. We use Sapi 5 to speak in our application. When user types a word to look for in the edit field, the listbox will appear range of similar words. I don't know why my application responses very very slow. Dang
