Radoslaw, I must have missed the mail you are referring to... Searched my entire mailbox for the word 'hole'... must admit was a bit scared what might turn up, but alas... nothing, if you could please pass me the mail you are referring to, so I can get a better picture, maybe I spoke too quick when I answered your email.
