moffitt -- welcome to the site and thank you for taking the time to post.
First, i think you must be talking about Screenshot Captor, because i don't think MiniCap has any blurb or nag or anything. at least not to my memory.
If you are talking about Screenshot Captor (the big brother of MiniCap), then the situation is a bit harder to explain. My big apps, like Screenshot Captor, pop up a quick welcome message the first time you run them, and then will start to ask you to download a *FREE* license key after about 10 days; to get that you just come to our site and visit the license key page
. Once you put that in you shouldn't be reminded again or see any sign whatsoever for 6 months
, at which point you can drop by the page again for a new key.
I know it's confusing, but the attempt is not to nag people to force them to donate -- but to try to at least get people to realize that our site survives only through the donations of users, and to make sure they don't at least visit our site to learn that if they are going to use our software.
