135798 - Mousewheel settings should not affect the file selection dialog

Status: NEW

(Firefox :: File Handling, defect)

Description

[Mark Volpe]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.9+) Gecko/20020401
BuildID:    2002040108

When the mousewheel is used in the file selection dialog, the file listing
scrolls by however many lines are specified in the mousewheel preferences. With
the default setting of 5, this is not a problem. However, when a user changes
this to 10 (so his web pages scroll faster), the file list will then scroll 10
files at a time when using the wheel. Since the window only displays 7 files,
the next 3 will be skipped, and appear to be missing until the user reveals them
by adjusting the scrollbar.

Reproducible: Always
Steps to Reproduce:
1. Go into mousewheel preferences, set it to scroll 10 or more lines at a time
with no modifier key.
2. Select File|Open or Save As. Go to a directory with a sufficiently large
number of files.
3. Using only the wheel, try to select the very next file in the list (the one
just beyond the last "visible" file)

Actual Results:  If the mousewheel setting is sufficiently high, you will not be
able to access certain files in a directory using only the wheel.

Expected Results:  All files should be accessible with only the wheel; the file
listing should be prevented from scrolling more than one page at a time.

This makes sense.

Just because you want to scroll pages by large chunks, that should not make the
file dialog scroll that much. 
completely two different things.

Still here in 2005.  Just a friendly reminder to poke anyone who's forgotten
about this bug.  It even appears in the new file selection dialog I have on
firefox 1.5b1.  One would imagine the best setting for this would for a single
scroll would scroll the entire page (7 entries for me currently), or the entire
page-1 or 2 entries.
