Sometimes it'll advance a few lines (or a few pages!), and sometimes it'll back up before it starts printing. Als

      • Hi I reference the API provided by a dll. Our application wraps around the dll and uses its API. However, at a certain point a call to a method to write a file can cause the dll to raise a modal error message. This stops our application until the error message is clicked and execution can continue. It's a complete showstopper for us! Is there any way I can trap this and stop the modal er
