IE will open PDF files internally? I thought all browsers just used the default PDF program (usually Adobe, though I have reset mine to be Foxit).

Upon checking, I see that my Firefox has an Adobe plugin(6.0) installed, and will use that as the default! I hadn't noticed, as I usually download the .pdf file and open it in Foxit....hmmmm....I need to see how I can override this.

In Opera, there is a dialogue box in preferences, where I have told it to use Foxit, so no matter which way I go, Foxit is used. If it requires Adobe Reader, I would have to download it and manually open it in Adobe.
