It's a pity that such an exciting, interesting forum can sometimes grind to a complete, lengthy HALT because people don't use the quote "if correct open house". We must consider that participants live all over the globe within different time zones so perhaps we should consider this Thread as 24/7 and before we 'sign off for bed/work' consider who might still wish to participate. This is in no way directed at anyone in particular and I hope no one finds my comments impersonal or critical.
