69812 - Keyboard scrolling gets disabled.

Status: RESOLVED DUPLICATE of bug 58250

(Core :: DOM: UI Events & Focus Handling, defect)

Description

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; 0.8) Gecko/20010215
BuildID:    2001021508

Normally you can scroll a page using the arrow-keys, but following the steps
below make the arrow keys nonresponsive, and you have to scroll by mouse (or do
the workaround to reactivate).

Reproducible: Always
Steps to Reproduce:
1. Open Mozilla and another program window or a second Mozilla window.
2. Go to any URL that has a page long enough to scroll. Don't do anything after
pressing enter, let the page load.
3. Click on (or ALT-TAB to) the other program/Mozilla window.
4. Swap back to the first window.
5. Keyboard scrolling doesn't work. Clicking on the page doesn't help.

Actual Results:  Keyboard scrolling stops working.

Expected Results:  Keyboard scrolling should work.

There are many ways to get this bug. Basically every time the browser gets a new
URL in any way, if you swap windows while it's loading the URL, when you swap
back keyboard scrolling doesn't work. The same bug has occurred for a long time
on various versions, and has been tested on Win2000 WkSt (SP1) and WinNT4 WkSt
(SP6a). Mozilla is the official release 0.8.

Workaround: Click on the URL-field=address bar, then click on the displayed
page. Keyboard scrolling reactivates, works every time.
Woraround2: Try to scroll the page while it's loading. Even if there's not
enough to scroll, this makes the keyboard scrolling work even if you swap windows.

over to event handling.  I think this is already covered by other reports.

Sorry if spamming but isn't this related to bug #30841 ? Could the reporter tell
us if text fields are unusable too? If yes, this is another way to disable
keyboard (besides double right-clicking).
