If a COM wrapped Java bean is instantiated at runtime using UserControl which basically calls Controls.add.
This UserControl is loaded in Internet Explorer. Events from instantiated
bean are received using Microsoft VBControlExtender.
In this scenario, "Enter" and arrows keys are not working (but
"Shift +Enter" is working).

Note that this problem has already been investigated as part of bug ID 4664403,
but since this is a separate issue from the issue treated in that bug, this new
bug has been opened.

A test case is attached.

When the testcase is using the BlueBox control to look after the ActiveX
bridged bean, I am getting no key down events within the ActiveX Bridge.
When the bean is hosted directly in the html page (as per the original
testcase, I was managing to get events and process.
