Save Menu Forces Sub-Menus (Child Menus) Back To Parent Menus in IE 9.0

[webby 2]

The following issue appears in Internet Explorer 9.0.8112.16421 (current version).

In Appearance->Menus for both primary and secondary menus, when you try to define a sub-menu by drag-n-dropping to the right in the menu definition box, it shows indented properly. However, when you click Save Menu, all sub-menus return to being parent menus.

The only way to get the sub-menus to work was to edit them in another browser. In this case, I used Internet Explorer 7.0.5730.11 and it worked properly.

No plugins, default theme? Can someone else provide confirmation?

Same problem with no plugins as with plugins.

Using the Weaver theme. Checked with the theme author who confirmed the theme would have no effect on this issue.

Can't reproduce with the same IE version in 3.2.1 or 3.3 with or without Weaver theme.

My steps:

1. Drag a child menu item to the right.
2. Click "Save Menu". The menu hierarchy is displayed correctly.
3. Reload the page or reopen it from the admin menu.
4. The menu hierarchy is still displayed correctly.

Can't reproduce neither.

Same steps as Sergey. Also tried both updating an existing menu or creating a new one.

Works for me too.

I'm having the exact same issue on Chrome 17.0.963.56, no active plugins, default theme, WP 3.3.1.

I then tried it with Safari 5.1.1 and had no issue creating a secondary menu. When I flipped back to Chrome, I just slightly dragged the menu item to the right (the one I successfully moved in Safari), then after I clicked 'Save Menu' the item was no longer a secondary menu.
