Not recognising additional ino file when compiling **SOLVED**

I have a project with two ino files, the main and my libraries. One day everything compiles beautifully and the next I get an error message: ‘ReadConfig’ was not declared in this scope. ReadConfig is in my library file. (After much hair pulling) I go to Dropbox and restore the project from two days ago, do a file compare on the two main ino files and discover a block comment that left the closing brace of an IF statement uncommented i.e. I now had an extra closing brace. I must have commented it out and not compiled at that stage.

As George Bush said to Hillary Clinton on inauguration day “That’s some weird s**t”.

I know that these things cause misleading error messages but I think that this one takes the biscuit!
