This is happening on my new month year old computer as well as my 10+ year old computer.
The behavior is exactly the same on both computers when using Gvim to open a .txt file. (I have not checked other kinds of files). While looking at the file in a Windows explorer directory in detail mode, I see the modification date updated to the present moment at the instant I open the file. This happens when opening the .txt file by: :r filename <enter> or by using the menus: File>> Open...>> Edit file>> select filename>> Open ----------- I double checked the behavior by Updating Windows and uninstalling my 32x Vim install and re-installing a 64x Vim install. I also update Windows 10 to the current version. I again saw exactly the same behavior. (Please, a few of you try this and report the outcome to my current thread about the issue in VIM_USE, and I will take those and update VIM_DEV.) Here are the details of my installation of Vim and Windows 10, however it seems to happen on some different recent versions of Vim and Windows: GVIM---- Signed 64 bit installer gvim_8.2.1444_x64.exe :version VIM - Vi IMproved 8.2 (2019 Dec 12, compiled Aug 13 2020 22:02:15) MS-Windows 64-bit GUI version with OLE support Included patches: 1-1444 (full version less .bat files) WINDOWS 10 Home---- 2020-08 Cumulative Update for Windows 10 Version 2004 for x64-based Systems (KB4566782) Successfully installed on 8/14/2020 2020-05 Microsoft Edge Update for Windows 10 Version 2004 for x64-based Systems (KB4559309) Successfully installed on 8/14/2020 2020-08 Cumulative Update for .NET Framework 3.5 and 4.8 for Windows 10 Version 2004 for x64 (KB4569745) Successfully installed on 8/14/2020 Windows 10 up to date - 8/14/2020 -- -- You received this message from the "vim_dev" maillist.
