Probably inadvertent, but Eudora has determined that something is covering all or a significant portion of an ad. The software is designed to notify you when this happens (Eudoras just doing its job).  If you uncover the ad, this window wont keep popping up. Youd like that, right?

Were always working on good stuff back at the home office, and its the ads in Eudora that pay the bills while we continue to develop the software.  Weve worked hard to make sure the advertising isnt annoying and we genuinely hope that you are not deliberately trying to cover the ads because theyre bothering you.  Of course, you can pay us for Eudora by choosing Payment & Registration from the Help menu and clicking on Paid Mode (costs money, no ads).  Or you can remove whatever is obscuring the ad and well shut up.
