Hi Alan,

thanks for your reply! :)

...and I thought it was me being too limited to see the real truth
behind that what it is The Matrix.

But it was only a deja-vu....oh wait! It was NO deja-vu ... no 
glitch in The Matrix...we had similiar emerge-ncies in the past. ;)

I will see how far I can go...I was warned to use 060 of boost...

Best regards,
Meino
