I'm not sure I know what I'm talking about, but I think you need a break statement at the end of each case. Otherwise I think it executes all the cases starting at the one that matches. So for example in your code if id is equal to wxID_SAVE then I think message is getting set to "Save" then to "Save As" followed by "Print Setup" all the way down to "Exit".

So add a line that reads break after each message = ... line. For example:

case wxID_OPEN then 
    message = "Open" 
    break 

By default, control flows to the end of the switch block when the next case is encountered. The default behavior can be modified in two ways. The default for a particular switch block can be changed so that control passes to the next executable statement whenever a new case is encountered by using with fallthru in the switch statement:

switch x with fallthru do 
    case 1 then 
        ? 1 
    case 2 then 
        ? 2 
        break 
    case else 
        ? 0 
end switch
