--- Comment #17 from Maik Qualmann <metzping...@gmail.com> --- The error code 1223 means "ERROR_CANCELLED". This is probably due to the fact that the dialogue was canceled by the user. If I try to open an unknown file type, I get a "modern" dialog with the suggestion to search the Windows App Store. Can you try to open an unknown file type, e.g. ORA, XCF or the like. What error message do you see? Maik -- You are receiving this mail because: You are watching all bug changes.
