Question: Do you know any PDF reader which remembers the last page for each document? 

The usage scenario should be something like this:

* A new PDF file is loaded into the reader
* The PDF file is opened on page 0
* Reading, reading, reading ... Reading finished at page 37.
* Reader closed
...
* The same PDF file is loaded into the reader
* The PDF File is opened on page 37

I don't need multiple bookmarks. Just one is enough. Any tips?

Answer: 
[**Foxit Reader**](http://www.foxitsoftware.com/pdf/reader/reader3.php) does that and it's free!

**[PDF-Xchange Viewer](http://www.docu-track.com/home/prod_user/PDF-XChange_Tools/pdfx_viewer/)** does just that (and not only for the last opened document, but all documents). In addition you can create your own bookmarks.

PDF-Xchange Viewer is freeware and a portable version is available.
