Recreate: Open two Sublime text editors. If one has an unsaved file, and you attempt to close the whole editor, it will ask you “Do you want to save xyz.json, Yes/No?” in a popup window. Now, don’t click anything, but pretend you never noticed that popup and just went to the other Sublime editor to work away.
While working, you highlight some text, use ctrl+c to copy this text, and then try to paste it - but instead of the text you highlighted, you get:
"---------------------------
Save Changes?
xyz.json has been modified, save changes?
Yes No Cancel
---------------------------"
pasted in your code! Heck of a strange bug, but that’s what happens to me! Anyone else?
