I've made excellent progress cleaning up the undefined references in the project, and now I'm left with one that's a little frustrating. In several class libs, there is an undefined reference for the same bitmap file. However, when I use a search utility like GOFISH to scan for this file name, I come up with nothing.

Do I really have to iterate through every class in these libraries to find the reference or is there another way you can think of to narrow down where it would be?
