I’ve had this issue for a while, and it hasn’t resolved with updates. Not sure what causes it.
But if I have Aseprite running for a few hours, the Enter key stops working within it. It stops working for everything – I can’t use it play/pause animation, or to select the “OK” button in popups, or to confirm number input into menus, and can’t use Enter to confirm a rotation/transformation. The Enter key just stops responding entirely for the whole program. I haven’t found any pattern to how or why this happens, and it seems to only be the Enter key.
Only affects Aseprite, as I can open up any other program (text editor, etc) and Enter key works fine.
The only solution I’ve found is to close the entire program and restart it. A minor annoyance, but doable.
