there's the difference(s) between how sd and I respond. 1. Sd, you hope to support your own position of two ts being okay. I haven't responded to these threads until now because I couldn't be honest and supportive. So different agendas. 2. Your solution fits into a nice mathematical logical box. If a then b. Therefore your way MUST be correct. But feelings are messy. I can't believe that's me saying that. I go more for reading between the lines, what is the OP hinting at but not saying. 3. And that's why people like SD's posts better than mine! You're more supportive -WAY more. I more tend to say the wrong thing at the wrong time. But hey - I'm old, who cares?! I love PC so much.
