Hi cricket, from Davey in Toronto..... I see you've been educated about GG... good... I must also provide a warning... This place is hazardous to your sense of time. I spend more much time talking to this wacky and wonderful collection of people than I do my co-workers, and during a time when I should be getting some of the things done which pay my salary (work, you know). You, too, may get hooked, if you're not careful (and even if you are) **GRIN**
