I use a Windows app called "AutoHotkey" to input text from the keyboard. One of the input assistance settings I have is to enter the date and time with Ctrl+D. When you press Ctrl+D, a timestamp is inserted at the text cursor position in the format YYYYMMDD-hhmmss. The Western calendar year is displayed at the beginning, which is very Japanese.
Now, when you do this with the Windows app Sticky, the date is inserted as a strange string of numbers. For example, if the date is "20250704-083530", it becomes "007040834". When I tried this every second, Ctrl+D line break, Ctrl+D line break, Ctrl+D line break, ..., the right end of the string was sometimes one digit away and sometimes not, and the line break after that was a paragraph break or an intra-paragraph break, and it was not consistent.
This phenomenon does not occur in other apps. (You can see how little I've used Sticky up until now.)
What should I do when such a minor but critical problem occurs? One option would be to use the Windows feedback form to complain to Microsoft. But I don't think the people who are busy developing AI would listen to such a trivial complaint.
So I made this short comment into a topic. I'm writing this in English because I have a faint hope that Microsoft's search crawler will pick up this comment and Copilot will notice it when it updates its language model, but I guess that's a long shot.
