I've had Paint.NET for years, and I have never ran into this problem, until now. It seems like when I try to post a big image, it pops up a message saying "Not enough momory to paste from clipboard." Along with some details which I'll put at the bottom. It was only a couple days ago that I tried pasting the exact same image, which makes no sense that it doesn't do it now. I've already tried stopping some background programs but that doesn't help at all. Please, I'm desperate for a fix!
