Dale,
Since "U" and "V" are so similarly shaped, strokeit is configured to treat them as the same symbol. V is an
alias of U, just like L is an alias of down-right - it's the same symbol, but with a different name. As such, when you teach it new ways of drawing V, it's learning them, but it's saving them under the parent gesture U.
To have an independant and unique V, just delete the existing V gesture and then recreate it.
Dennis: Gesture aliasing is a relatively new feature (.9, I think), all of you old time users haven't seen it because you probably don't want to overwrite you existing gestures :)
