Apologies if this has been asked/answered before -- but there are 42 pages here!
For some odd reason, when I save a file, eventually I get these weird grayshaded dots surrounding the lines in my document. Weird. The same thing happened with MS Paint (which is why I went to Paint.Net in the first place. It doesn't always happen, it seems to happen when I paste in a photograph or something else.
Thanks for your help!
