Hi Philippe,

Thanks for the response. Just to bring this thread to a full conclusion: In my original email that started the thread, I had written that we had found that it did seem to work. Now when you say it doesn't, do you mean, it would crash right away, or it would just work by luck, but would be unreliable?

Cheers,
e.

In case they are not written explicitly, please be aware that my greetings and farewell are inherently implied in this email.
