TNX a lot, guys, that was the first thing I tried, it doesn't do the job. But after some restarts (and other things, unrelated to Paint.net) the original bugger window returned. Beginners luck, I guess, LOL.
There's another thing that I can't master it: When I open Paint.net, import a file, do some things on it, and want to save it-Paint.net asks me where I want to save it, by opening a small window. After choosing the folder+click on the right button in the drop'window, and clicking ENTER, it goes where I want it. However, if I import a new file, the click on the "safe" button from the Paint'menu just sends it to some undisclosed destination. And DEFINITELY not were the last file was sent. Well, I learned that I must close Paint.net, and open it again for every new imported file. But it also means to adjust all the settings again.
Is there a way to make that drop'window (which asks where to safe the file) appear again, without closing and opening Paint.net every time, please?
