Okay…so I dowloaded Acrobat Reader 7 and now the Response.WriteFile() solution works in both browsers, and I can’t get BinaryWrite() to work. This is so ghetto.
UPDATE: Okay…so now both work on reboot. On files from my local machine I can’t make a determination as to which implementation is better (faster). I will run tests tomorrow when I get to the office, but does anyonoe know or have an opinion?
