Here's a simple page with 2 textboxes and an AJAXUploader control. Textbox1 is in an UpdatePanel (with UpdateMode=Conditional, AutoPostback=true) and Textbox2 is simply on the page (with AutoPostback=false). First, run the page without the AJAXUploader to see how the page should behave. Add the AJAXUploader back and you'll see that adding the control causes the page to misbehave.
