I really enjoy using Paint.NET, but just today I started having a terrible issue when saving files. No matter the image, when I try to save it the "Save As" window appears, but immediately stops responding. After 5-10 minutes of waiting, it will come to again, but the next button I press there (either to enter a folder, create a new one, or to actually press the "Save" button) will cause another 5-10 minutes of not-respondingness. I've looked in Task Manager during this time, and Paint.NET is not using much of my computer's CPU, RAM, disk R/W etc. even though there is plenty available. I have an SSD, so disk speed should not be an issue. I am running up-to-date Windows 10 with the latest version of Paint.NET (4.0.9; 4.9.5848.30436). Fortunately this issue first occurred with some minute pixel-art, so I was able to recover most of my work by taking a screenshot during the crash.
Thank you in advance!
