Thanks Martin, I applied the patch.

The problem I was having was the IO Error, sorry for being vague.

The part I don't understand is I should not have had other threads running (and definately should not have had the logger being used outside the main thread.) Can the problem occur with just one thread? I was running under the debugger in wing, I don't know if that might cause this problem.

Anyway if I find out anything else I'll let you know. If you don't hear from me then everything is working great.
