That solved the issue. Thanks. Indeed, I could have clicked that button a while ago. (Note to myself: Never click any buttons in Paint.Net plugins unless it's absolutely necessary. )
Hi, every time I want to save a pgm image in Paint.NET, this website open just after the "Save Configuration" dialog appears, undemanded. It just opens that website in my browser, although I didn't click any buttons or so. This is very annoying. Can you fix it or forward this to the developers of this plugin? I couldn't register in their forum, and found no contact details.
