Thats not the only problem. I get problems when loading an image when
multithreaded. As previously posted.
If I could build the darn thing, I might look into fixing it.

Subject: Re: Multithreaded failure
I moved the creation (and destruction) of the Driver object inside the
method. Also I had forgotten that in Apache SOAP, you can control object
lifetime. So I changed it from Application to Request, so now each request
gets a fresh instance of my class.
This works, but I'm not happy with it. My question is this, if I have a
Driver object as a global inside my class, will it be trounced by another
instance running in a different thread?
