Status: RESOLVED INVALID

(Camino Graveyard :: HTML Form Controls, defect)

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en; rv:1.9.0.16) Gecko/2009120123 Camino/2.0.1 (like Firefox/3.0.16)
Build Identifier: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en; rv:1.9.0.16) Gecko/2009120123 Camino/2.0.1 (like Firefox/3.0.16)

A long select form control (<select> with <option>'s) doesn't behave properly when it is scrolled with a mouse. Scrolling seems to 'freeze' the control and it doesn't respond to clicks either off the control or on an option. Pressing escape removes the control focus and returns control to the user.

Reproducible: Always

Steps to Reproduce:
1. Go to http://www.malts.com
2. Click on the 'year' select drop-down on the right
3. Without clicking, scroll with a mouse wheel. Try to select a value or click off the control. 
4. Press escape to remove focus from the select.
Actual Results:  
It 'froze' on the control

Expected Results:  
Select the option clicked or hide select drop down when clicked outside the control

This works great for me in a recent nightly and in 2.0.1. Does a fresh profile make any difference?

Nope. I tried originally in 2.0.1 and just tested it with Version 2.1a1pre (1.9.0.17pre 2009120701), nightly. Exact same problem. How'd you get it to work?

I'm on 10.5, by the way; it's possible this could be 10.6-only, but I'd think we'd have heard something from one of our 10.6 users by this point...

3 & 4 both WFM on 10.6.

Do you see anything in the console.log (in /Applications/Utilities/Console.app)  when this happens?

Smokey - Nope, nada

Ben, can you try a fresh OS X user account? I suppose this could be something weird on your account. Do you have any software installed that might be messing with mouse or menu behaviour?

Chris, thanks for the follow up. I tested it with a fresh user account and found that it behaves correctly! On the original account I had xGestures installed, perhaps that was interfering. I re-tested it on my original account and found that I have the same problem with Safari. I think it's safe to chalk it up to xGestures, I'll file a bug report with them. 

On the fresh account:
- The mouse wheel successfully scrolls the page
- When a select control is clicked the mouse wheel scrolls correctly. I noticed that the mouse wheel will ONLY scroll the select and not the page as long as the select is displayed. Also the selects will be as long as the window allows.
- The select drop-down can be removed by clicking off.
