Status: VERIFIED DUPLICATE of bug 97283

(Firefox :: General, defect)

Description

[Isomorphic Software]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.6) Gecko/20050317 Firefox/1.0.2

Mozilla only supports scrolling of elements via the mouse scroll wheel for some
elements.
If you have a simple DIV with overflow set to "scroll", "auto", and contents
that exceed the specified size of the div, the div becomes a scrollable area. 
Attempting to scroll the DIV with the mouse-wheel has no effect - it will
instead scroll the page.

Mouse wheel scrolling IS supported for some other elements such as IFRAMEs.

Reproducible: Always

Steps to Reproduce:
1. Open the attached test case
2. Position the mouse over (or click on) the scrollable red DIV
3. Rotate the mouse wheel to scroll the DIV and view it's content.

Actual Results:  
The page will scroll

Expected Results:  
The DIV will not scroll

Note that the IFRAME on the same page will scroll if you rotate the scroll while
while focussed on it.

Please search before you file a bug.
(and also test a recent trunk build because FF1.0.X is from a very old branch)
