We run software that will trap this and let us know about hidden files you create. They'll be gone quickly. :) once win95/98 goes away, and NT becomes the standard, this won't happen, ever, because NT isn't going to let everyone write wherever they want, only in directories where they have permission to write. Which solves the problem for me, but makes yours much more problematic. :)
