Hello Gert,

Thanks for the report.  It now looks for History in the session.
I also fixed the problem where it wasn't showing anything if it couldn't 
resolve the hostname.

As for the internal server error, is there something in the error log 
you can email to me when this happens? or to this list if you don't mind 
sending it here.

I went through the code today and changed a few things, so maybe the 
changes i made will also fix that problem as well.

For anyone that has already downloaded it please grab the new tag here:

or the patch here:

If anyone experiences any problems, please let me know.
Thanks, Don
