Are there a known issues when working with events from .NET 4 COM assemblies within ArcMap?

For example, when using IDocumentEvents_Event from a .NET 4 assembly in ArcObjects, the event appears to work properly, but disables the standard right-click context menu behavior in ArcMap. Changing nothing in the assembly except the target to .NET 3.5 or .NET 2.0 will "restore" the default behavior. Is this a COM issue, or an ArcObjects issue? If the latter, is there a potential workaround?
