Re: wxwebview edge

No ideas?

I think there was some talk a few weeks ago about idle processing and edge
backend, but I can not find it
and don't remember what it was about.

I use idle processing to execute commands from the erlang threads so that
might be involved in some way,
but that part seems to work, I just don't get any window events at all.
