plonq | Unclear on the concept?

I am making some minor changes to an editing program I wrote a couple of years back. All was well until I called up one of the forms and noticed a check box at the bottom of the form. While a check box at the bottom of this particular form would not be out of place, the caption next to it simply reads, "Don't click here if you are unclear on the concept."

...!
I am guessing that this caption gets changed at run-time. I suppose i will have to dig into the source code to find out what it is actually for, just in case it is one of the things I need to change today. On the other hand, with a caption like that it will probably be a bit of a let-down when I learn its real purpose.
