Hello, I have just experienced the same problem today (after years of using Geany seamlessly). Can this be related to the fact that I have tried to input Unicode characters like "É" just before (unsuccessfully, by the way...), which I think I had never done before? At each attempt of file saving, I get a new file named .goutputstream-XXXXXX instead, with the content of the file I am trying to save. Yours, Maxime
