IE is unfriendly sometimes.  Here are a few tips I have found to be useful:

1.  Assure the URL the browser sees is "[something].pdf", i.e., rename 
your method so that it ends with ".pdf".  You can set the name of the 
actual pdf file downloaded with the "Content-Disposition" header.

2.  Making Content-Disposition say "attachment" instead of "inline" may 
help with some versions of Acrobat Reader.

3.  Set the "Content-length" header.

As an example, I am having success with something like the following:

theFile = asPDF(dummy)

REQUEST.RESPONSE.setHeader("Content-type","application/pdf")
REQUEST.RESPONSE.setHeader("Content-Disposition",'attachment;filename=ThisIsTheRealFileName.pdf')
REQUEST.RESPONSE.setHeader("Cache-Control",'private')
REQUEST.RESPONSE.setHeader('Content-length','%s' % len(theFile))
REQUEST.RESPONSE.write(theFile)

hth,
