446472 - Mouse coordinates are incorrectly handled when the Flash component is rendered on top of an IFRAME and has wmode=transparent

Status: RESOLVED WORKSFORME

(Core Graveyard :: Plug-ins, defect)

Description

[Aaron Charbonneau]

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.0.1) Gecko/2008070206 Firefox/3.0.1
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.1) Gecko/2008070208 Firefox/3.0.1

PROBLEM:
Mouse coordinates are incorrectly handled when the Flash component is rendered on top of an IFRAME and has wmode=transparent. As long as you have the mouse pointer outside of the IFRAME, the mouse coordinates are interpreted correctly (e.g. you can pick the right color from the color picker); but after you get on top of the IFRAME area, the mouse coordinates that the Flash component receives are not the right ones anymore.

Reproducible: Always

Steps to Reproduce:
METHOD:
Steps to reproduce:
1. Create a Flash component containing Color Picker (or a Drop-down)
2. Take a HTML page and place the Flash component inside a DIV with top=0; left=0; height=100%, width=100%, z-index=10
3. In the same HTML page place another DIV with top=90px; left=0; height=100%, width=100%, z-index=5; inside this second din insert an IFRAME (e.g. <iframe src="http://www.google.com"></iframe>)
4. Preview the page in Firefox 2 or 3 on Windows
5. Try to expand the Color Picker and pick a color
6. The hovered color in the Color Picker is located upper with 90px than the mouse position
Actual Results:  
Mouse coordinates are relative to top-left corner of the IFRAME rendered below the Flash component 

Expected Results:  
Mouse coordinates should be relative to top-left corner of the browser's view-port 

This occurs using Flash 9r28, 9r124 and Flash 10 Beta.  Does not happen on MAC OSX Firefox.  This also does not occur on any other browser that uses the Flash Plugin, such as Opera and Safari

Attachment: Flex Project that creates a Flash component on top of a Browser iFrame

Run Test_FF_MouseCoordinates >> bin-debug >> Test_FF_MouseCoordinates.html after you have unzipped the folder to show the bug.  Attempt to use the color picker at the top to show that the mouse coordinates are off.

I can reproduce this problem on Windows XP (in FF 3.X and FF 2), but
not on OS X or Linux.  My Flash plugin version is 9.0 r124, which I
believe is the latest "release" version.

The bug doesn't appear to repro as of FF 3.5 on my Win7 and WinXP box (with Flash Coral 10,0,r45,002).
