This boiled down to a case of too much hand holding. When multiple possibilities exist having the same name Code Insight would show nothing.
I changed it to drill into the first item it can find in the list matching what you've typed. If it guesses incorrectly you can always force the object you want by selecting it from the pick list and then typing period. At least this way something will be shown, always, and the guess will be right at least some of the time. :-) This is in place for next beta.
