Foxit Reader 1.3 beta build 0708: Page keys don't move correctly

Tested version: Foxit Reader 1.3 beta build 0708 only (the bug might be present in the previous versions; I just don't know)

Steps to reproduce:

1) Open a PDF file that is multiple pages long.

2) Select View/Fit Page from the menu.

3) Go to the first page of the document (Ctrl-Home).

4) Press PgDown repeatedly.

After a few PgDown keypresses (e.g., 20), it will become very obvious that the window no longer shows a complete page. Instead, it shows the end of one page and the beginning of the next. In other words, the PgDown key advances by a bit more than an exact page in Fit Page mode, and the window runs out of sync with the pages.

Exactly the same problem exists with the PgUp key, if you go to the end of the document and start paging it backwards.
