More likely the Perseids than the Leonids.  Or probably, since you're
on Windows, the Leonids from last year?  :)

I'm aware that the hint comes too late but maybe it's helpful whenever
you encounter such problems in the future:

Before you change anything in the registry manually, it's best to dump
the content of the registry to a text file.  I don't have Windows and
therefore can't provide precise instructions.  AFAIR there is an
"Export" entry in the "File" menu of regedit.exe.

The created text file is UCS-2 encoded, if it screws up your favourite
text editor, try another one.  Emacs is always a good choice.

Such a registry dump is quite useful.  Especially if you create
another one after you modified the registry and the system behaves
differently then.  You can use standard tools like "diff" in order to
compare the two files.  It helps to find out what you've actually
changed and which of your changes solved the problem.

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
