Sarge and company, For the past two days, each time I've opened Eudora 4.3, which I've previously registered in sponsored mode, I've received a message informing me that I don't seem to be receiving ads, and including a link to the Qualcomm website. Also included in the message is a veiled threat that without ads my software will "eventually" revert to Light mode, with its diminished feature set. The Qualcomm link simply takes me to a download page, offering a number of variants of the Pro version at a price. I don't want to buy it, which is why I downloaded innumerable versions of the beta and registered in Sponsored mode in the first place. I haven't touched the Eudora installation in weeks, so that's not the cause of the interrupted ads. Nor have I tried in any way to delete, block or disrupt the ads - they're small and pretty innocuous and I just ignore them. I'm wondering if Naviscope, an internet utility which I installed several days ago, could be the problem. One of Naviscope's features is that it blocks banners and popup ads on websites. It never occurred to me when installing it that it might interfere with the several ad-supported pieces of software I've acquired. Any suggestions welcome! Thanks, Christopher Brooks Franconia, NH
