Forum Post: Inactive code not highlighted in long file.

I am running CCS 5.3.0.00090.

I inherited a long file (7000+ lines including comments) with a lot o0f conditional compilation.Unfortunately the inactive code is not highlighted, although it once was. Also, If I reduce the length of the file by hacking out half of the content, the highlighting returns.

I cannot find the setting that deals with long files, but I believe there is one.

Can anyone solve this riddle?

Thanks
