[erlang-questions] Re: Debugger fault at startup.

[Dan Gudmundsson]

Hi

et_viewer might be another problem, I did some last minute patches to
make it run at all on windows.
It was taking some shortcuts that only worked on linux.

It's not much I can do without some more info, wx works here, both on
linux and windows.

I have not made any changes that should make it start causing those
troubles, I have added new functionality
in R14B but that shouldn't be called until the user are using those
functions from erlang, i.e. the initialization part
is the same as before.
