User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5 (.NET CLR 3.5.30729)

This bug only happens on my two WinXP Pro Lenovo notebooks, an R61 and a T61.  Other non-Lenovo PCs I own, do not exhibit this bug.
This bug exists in Firefox 3.5.5 (latest version) but has existed in all versions of Firefox 3.x.  It does not exist in Firefox 2.x  
Bug occurs at many web pages  -- however it is only relevant if web page is more than one printed page long.

Bug:
when using Print Preview, I can use PgDn and PgUp keys to scroll up down the images of the pages as they will print.  However, if I change the print Scale field, e.g. change from 100% scale to 90% scale, then the scale field stays highlighted, and the PgUp PgDn keys are no longer functional.  I can use the mouse with the vertical scroll bar on the right, to scroll up down pages previewed, but not the keyboard.  Clicking on part of a previewed page, does not release focus of the Scale field.  I can click on the Portrait or Landscape buttons, and the page preview updates; I can change the scaling to another value and the page preview will correctly show the new page previews.  But I cannot get the PgDn or PgUp keys to again work, to step through displaying the preview pages.
If I close print preview, and then print preview again, I can now use PgDn PgUp again, as long as I do not change the page scaling. 

(I realize this may sound like a strange bug, or at least maybe a hardware or hardware driver bug, given that it occurs only on some computers I own, not all.  OTOH, Lenovo is a large notebook vendor, so maybe there are other Lenovo notebook owners with the same problem, even if they do not use keyboard with print preview and thus, never noticed it.  Note: I did try updating all the drivers in both Lenovo notebooks. )


Reproducible: Always

Steps to Reproduce:
0. (obtain a lenovo T61 or R61 notebook computer)
1. print preview
2. use PgDn PgUp keys.  then change print preview Scale field.
3. use PgDn PgUp keys again after refresh.

Actual Results:  
PgDn PgUp keys not functioning

Expected Results:  
PgDn PgUp keys should still work

Dup of Bug 447624? (Print Preview Click Doesn't Focus)

You cannot get focus back on the print preview document after using the menu scale or orientation options. This breaks PgUp/PgDn on Print Preview
