Re: Re: process an event without a window

I did consider that, but I need the thread to run even if the __init__ 
raises an error.. I could wrap the window instantiation in a try/finally 
and still call the thread, but it leaves me with the same problem of not 
having a window to post the event to. I wasn't aware that you could bind to 
the wx.App so I'll try that and see how it works.
