Hi,
I just bought an E-Z Command Control and seem to have a problem with the whistle function.
I press the F2 button and the whistle goes on BUT STAYS ON after releasing the button.  I have to press the F2 button a second time to make it stop.  With an MRC Prodigy DCC Control the whistle stops the moment I release the F2 button.  Is this normal?  Is my E-Z Control defective?   
I don't want to send it for repair and find out that it is supposed to act that way!!!
Thank you,
