RESOLUTION
==========

WARNING: Using Registry Editor incorrectly can cause serious problems that
may require you to reinstall your operating system. I  cannot
guarantee that problems resulting from the incorrect use of Registry
Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys
And Values" Help topic in Registry Editor (Regedit.exe) or the "Add and
Delete Information in the Registry" and "Edit Registry Data" Help topics
in Regedt32.exe. Note that you should back up the registry before you edit
it.

To resolve this issue, follow these steps:
