Logic Flow Chart App

[Bob Sneidar]

Hi all. 

Anyone know of a good logic flow chart editor? I am having difficulty whenever building complex control structures. When I have 3 or 4 conditions that can be true or false, affecting whether or not I even check for conditions further down the line, I get lost pretty quickly. If I could visualize the overall conditional logic apart from the code I execute it would really help me I think.
