[Chris Raplee]

User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b2) Gecko/20050317

On my new hyperthreaded P4 selecting text, clicking in the address bar, or 
clicking a link will hang the browser for 6-12 seconds.

Reproducible: Always

Steps to Reproduce:
1. Select some text
2. Repeat 1 until browser stops responding to mouse/keyboards. 

1.a Alternately: click address bar and then click page repeatedly. 

1.b Alternately: pgup/pgdn repeatedly. 
Actual Results:  
App stops responding. Processor usage never rises above 14%, but the app takes 
up to 15 seconds to respond to the input. Confirmed in latest firefox, mozilla. 
Confirmed in firefox 1.0.1 and 1.0. 

Clicking 'x' (close button in title bar) causes windows to throw the "Not 
Responding" dialog: message loop not being processed?

Expected Results:  
App should respond to input in a timely manner. 

Brand new system, Firefox the first app installed after MS security updates. 
Video card: intel 82865G. Proc: Intel P4 HT @3.0 Ghz

Revised steps to Reproduce:
0. Preheat processor to 85 degrees celsius
1. Select some text
2. Repeat 1 until browser stops responding to mouse/keyboard events. 

Workaround:
1. Purchase system from reputable shop even if it does save $20 and a 10 minute
drive. 
2. Ensure heatsink is properly seated on processor.
