Status: RESOLVED DUPLICATE of bug 541309

(Core Graveyard :: Plug-ins, defect)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3 (.NET CLR 3.5.30729)

With the 3.6 update Silverlight support for the mouse wheel to zoom in and out of deep zoom images has stopped working. This is fixed by downgrading to the previous version. This problem may also be related to a bug reported that silverlight applications receive a scroll bar on focus. It seems mouse wheel events are not being passed to silverlight.

Reproducible: Always

Steps to Reproduce:
1.Install 3.6
2.Install Silverlight
3.Open a Deep zoom image such as the one linked in this report and try to use the mouse wheel to roll into or outfrom the image.
Actual Results:  
Zooming does not work!  Downgrade to the previous version and it does work.

Expected Results:  
The mouse scroll wheel event is used by Silverlight to zoom into and out from the current zoom level.

This works fine for me on Windows Vista with latest 3.6 (dupe of bug 541309?) but the problem is that it fails on trunk, but only with IPC enabled. :/
Maybe Jim knows if there is a trunk bug for this?

I have tested it on Windows XP and Windows Server 2003 and I have tested it on three different boxes with three different environments and it fails on all of them. Rolling back to the previous version fixes the problem in all cases.

Looks like this might be a dupe of bug 483136.

If it works on trunk without IPC, dup of bug 541309. I guess it is.

Okay thanks. Then the trunk issue will be solved by bug 483136.
