This is an Acrobat SDK question. You would best be served by posting it in the Acrobat SDK forum. The ActiveX control "AcroPDF.dll" doesn't have menus so you are using another method probably not subscribed by the Acrobat SDK. The "floating" menu that you are referring to sounds like what is called the "Heads Up Display". As far as I am aware there is no way to disable this toolbar but again ask this question on the Acrobat SDK forum.
