Just got a bootlegged batch of fresh Dried Frog Pills (pale yellow, not 
green) which does seem to do me a lot of good... [kwark!] sorry  ;-)

You know how it works: somebody in some scene uses a "smart" trick, 
which seems to work fine, and you mindlessly copy that into your own 
scenes, and it does seem to work... somehow, and then you tweak that 
"smart" trick to cover another need (close, but different) and lo! it 
just refuses to do what you expected. That is what happened to me. It 
took me an unusual long time to discover that it didn't work because I 
had been so clever as to cover up my tracks in such a way that it always 
"seemed" to work. I was sorely mislead by my tricky mind! One always 
needs a critical mind close by to get you back on the right track. 
Thanks Bill!
