Trying to use C# precursor directives for debugging purposes. 

I can add the IF/ENDIF just fine i.e. 

But when I try to add the associated DEFINE to use this the compiler tells me it must appear as the first non-whitespace character on the line. Which it appears to be but for some reason the C# compiler thinks line 1 has 1147 columns when it only has 14.

I tried refreshing the page but that didn't help. 

What am I doing wrong here?
