272854 - XML pretty printing "disappears" when clicking twice on middle mouse button

Status: VERIFIED DUPLICATE of bug 215762

(Firefox :: General, defect)

Description

[Jurre Thiel]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20041001 Firefox/0.10.1
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20041001 Firefox/0.10.1

When clicking on my middle mouse button (which normally enables  smooth
scrolling) at http://gathering.tweakers.net/rss/list_messages/983328, nothing
happens. When I click on it another time, the pretty printing "disappears".
Instead, I just see plain, unformatted XML. I still can't scroll and I can't
always get "smooth scrolling pointer" to disappear again.

Reproducible: Always
Steps to Reproduce:
1. View http://gathering.tweakers.net/rss/list_messages/983328
2. Click your middle mouse button, nothing should happen.
3. Click your middle mouse button once more.

Actual Results:  
I see plain, unformatted XML. I can't scroll, I can't let the "smooth scrolling
pointer" disappear.

Expected Results:  
Scroll Smoothly ;)

I'm using a Logitech Mouseman Wheel, connected to a PS/2 port, using default
Windowx XP drivers.

Trying to reproduce this (once more ;)), this step seems to be unneccessary most
of the time.

I also see this bug in Firefox 1.0 on win XP pro. All it takes is clicking the
middle mouse button on an XML document in pretty print mode. See for example:

Not a GFX bug.  This is a (now fixed, if I recall correctly) bug in the
smoothscrolling implementation in Firefox.  Please find the original and mark
this one duplicate.
