I'm having the same problem. I use Leech as my download manager, and I first thought it was because of Leech. But, when I turn that option off, the same thing happens. I have my OW set as Safari, and I find that for PDF files, I have to right click the PDF attachment and select "Download Link to Downloads." That works for me, but it would be nice if I didn't have to do the extra step.
