With the Mozilla ActiveX Control (1.7.1) embedded inside Internet Explorer, the
following happens...

When using HTML (or XUL) form controls (such as INPUT) within the Mozilla
control, ...

1.  The TAB key changes the focus to other controls within Internet Explorer,
not the controls within the Mozilla control.

2.  The BACKSPACE key causes Internet Explorer to navigate backwards through the
 browser history.

3.  The Arrow keys don't seem to function at all.

Because the Mozilla control uses ATL, I believe this problem can be resolved by
implementing the resolutions provided in the following pages...

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
Thank you for your help in this matter.
