644555 - No scrolling mousewheel and tabs wont react on clicking in FF4

Status: RESOLVED INCOMPLETE

(Firefox :: General, defect)

Description

[mrdummy]

User-Agent:       Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0) Gecko/20100101 Firefox/4.0
Build Identifier: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0) Gecko/20100101 Firefox/4.0

When i have loaded FF4 with some tabs on my Windows 7, and closes the screen down for sleep mode. It's on my laptop.

When i reopened it to work further, i want continue with surfing, but the mousewheel wont react, thus no scrolling page. I can only scroll with scrollbar on left with mouse drag.
The tabs are also not reacting on left click. I cannot go to another tabs to see the pages. The leftclick text selection works, and rightmouse menu pops up, also in the tabs.

After restarting FF4, everything works normally. With previous FF3.6, this problem is never happens, but with FF4, it happens once time already.

Reproducible: Couldn't Reproduce

Steps to Reproduce:
1. Start FF4 with some tabs open, normal surfing.
2. Close down the screen for sleep mode laptop
3. After some time, reopen screen and continue with surfing. Try move to tabs and scroll pages.
Actual Results:  
If the bug happens, you cannot go to another tabs with left click, and scrolling with mousewheel or touchpad scroll wont work. It looks the browser is blocked, but it's still running half good.

Expected Results:  
Without bug, you should normally scroll all pages with scrollwheel and clicking on tabs should not have problems.

The laptop used is HP TX-2550ED. Installed with W7 64bits. Runs fine and stable.
With FF3.6 i have not seen problems with tabs and scroll, but with FF4, it happens today already with no reaction on scrollwheel and clicking on tabs.

Perhaps there is some loss on focus inside FF4, after recovering from sleepmode laptop. I continue with FF4 and sleepmodes, so i can perhaps reproduce it again.
No critical bug, because i can still restart FF4 to recover it. But it's clearly navigation error in FF4 and might happens by some users with laptop.

Thema is pretty normal, it's only installation/upgrade over old 3.6.

Could you see if the issue occurs if using Firefox in safe mode:

How about with a new, empty testing profile? (Don't install any addons into it)

Changing platform to x86; since WOW64 in user agent indicates 32bit build of Firefox (platform refers to browser build, not OS).
