311532 - left mouse press pegs cpu

Status: RESOLVED DUPLICATE of bug 141710

(Firefox :: General, defect)

Description

[enolte]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8b5) Gecko/20051006 Firefox/1.4.1
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8b5) Gecko/20051006 Firefox/1.4.1

When the left mouse button is pressed and held, CPU utilization jumps to 100%.

Reproducible: Always

Steps to Reproduce:
1. Start ActivityMonitor (Applications|Utilities|ActivityMonitor).  Make sure
you can see the "CPU Usage" graph when Firefox is in the foreground.
2. Open http://www.mozilla.org in Firefox 1.5 beta 1 or beta 2.
3. Move the mouse into the page, say in the whitespace next to the "Get Firefox"
text.
4. Press and hold the left mouse button.

Actual Results:  
The CPU Usage graph shows 100% utilitization.  If the button is held long
enough, the CPU fan kicks in.

Expected Results:  
CPU utilization should not change.  Neither middle-button nor right-button show
this spike in CPU utilization.  Left-button press-and-hold shouldn't change either.

This occurs on a Mac Mini running Mac OX X 10.4.2 with both MS Intellimouse
Optical and MS Intellimouse Wireless Optical Pro.
