Status: RESOLVED WORKSFORME

(SeaMonkey :: General, defect)

Smooth scroll pref. UI is now on, but there is one usability issue which
prevents me to use the feature.

Reproducible: Always
Steps to Reproduce:
1. Enable smooth scroll. (in Edit/Preference => Appearance tab or set
'general.smoothScroll' to 'true' in about:config)
2. Click any text box of this page by mouse (bug alias box is a good choice)
3. Scoll forward/backward by rolling mouse wheel or clicking the main scroll bar.

Actual Results:  
The scroll is extremely jerky, laggy, or doesn't work at all. To bail out this
situation, steal the focus by clicking the exterior of the text box in browser
window.

Expected Results:  
Just scroll smoothly like when the text box doesn't have focus.


Page-wide scroll by keyboard isn't allowed in this case, so use mouse to
reproduce the bug.

Btw, filing bugs as "NEW" in browser-general is a good way to make sure no one
ever sees them....

As a bug reporter, I found this bug has disappeared (i.e. fixed by some other
change) between semonkey 1.8a - 1.8b era.
