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 (EudoraΓÇÖs just doing its job). If you uncover the ad, this window wonΓÇÖt keep popping up. YouΓÇÖd like that, right?
WeΓÇÖre always working on good stuff back at the home office, and itΓÇÖs the ads in Eudora that pay the bills while we continue to develop the software. WeΓÇÖve worked hard to make sure the advertising isnΓÇÖt annoying and we genuinely hope that you are not deliberately trying to cover the ads because theyΓÇÖre bothering you. Of course, you can pay us for Eudora by choosing ΓÇ£Payment & RegistrationΓÇ¥ from the ΓÇ£HelpΓÇ¥ menu and clicking on ΓÇ£Paid Mode (costs money, no ads).ΓÇ¥ Or you can remove whatever is obscuring the ad and weΓÇÖll shut up.
