The DropDown for a Combobox requires a view that can "float" above the Raptor layout window. This should be done by giving views a borderless top-level window. Implementing this on the three platforms could be nasty. Is this a view bug or a widget toolkit bug?

this is a widget issue. the widget kit probably needs to have a new widget type representing a popup child window. on windows at least this is a new type of window from the ones that exists. it's a new type of container window.

Setting all current Open/Normal to M4.

per leger, assigning QA contacts to all open bugs without QA contacts according to list at http://bugzilla.mozilla.org/describecomponents.cgi?product=Browser

Reassigning qa contact to petersen@netscape.com

I have added the support in the Windows toolkit for views having borderless pop-up windows. This needs to be done for Mac and GTK

Fixed in April 13th Build.
