    Hi Alexander Rotter,
    Thank you for your report. We have reproduced the issue. Unfortunately we couldn't fix this bug for near future release as fairly low priority and frequency bug. Please let us know if this bug fix is important for you and your business.

    Hello. Thanks for taking a look at the issue. I uninstalled all Flash Player instances from my workstation and reinstalled the latest release Flash Player from the link you provided. However, the issue still occurs. I've created a screencast (see attached ZIP with WMV inside) that demonstrates the problem on Flash Player 10,3,183,7 in Firefox 6.0.2 (my previous mentioning of Firefox 6.1 was a typo, I meant 6.0 - sorry for the confusion) on Windows 7. I used the same SWF I had attached in my original report.

    Thank you for your report. We have investigated the issue.
    Sorry but we are unable to reproduce this problem. Attachment is the screenshot(QEscreenshot.jpg). We found color changed. Could you please download the latest Flash Player version from (or Flash Player version 11 Beta 2 from ) and verify your issue. Apologize for any inconvenience.

    (Adobe, y u no let me edit bug or use JIRA for Flash Player bugs? ;) )

    Problem Description:
    Event listeners stop working and no longer react to their registered events when zooming by changing the z property and then changing stage.quality. In the provided example, both "willTrigger()" and "hasEventListener()" report that the listeners are still there but they don't react to the registered MouseEvents.

    Steps to Reproduce:
    1. Run attached swf
    2. Move cursor over central button -> color change on MOUSE_OVER/MOUSE_OUT
    3. Use mousewheel to zoom out until stage.quality changes to HIGH
    4. Move cursor over central button -> no color change and no trace output in console when debugging

    Actual Result:
    Event listeners stop working and don't react to their registered events any longer.

    Expected Result:
    Event listeners should work regardless of stage.quality or 3d transformations.

    Any Workarounds:
    Manually dispatching the registered events makes the listeners active again, as well as moving the central button around by 1px on the x/y axis.
