FD v. 7 problem

Hi, all. Every time I open one particular script, it is a dark color, as if I put sunglasses on or something, and I can't figure out why? My other two scripts do not do this when opened. It's not an adjustment I need to make on my monitor or anything. It's just the one file.

Any help would be appreciated because it's driving me crazy.

Thanks,

Jamie

Ah! My hero! Thank you so much, Chris. I have no idea how the background color got changed like that, but we're back to normal now.
