How many programming languages/development frameworks are you currently using?
TallGuyShort: I have to switch languages a lot too, but I've found that I don't have a problem as long as I use each language regularly. It's when I haven't used a certain language for a few weeks / months that I confuse it with other languages.edit: For the record, I frequently switch between Flex, Java, PHP/SQL, C, Lisp / Clojure, and a couple of other scripting/markup languages.
