Hover over a + 1 and you get a "The editor could not be opened due to an unexpected error: File is a directory" in an empty tab and an OK "button".

I'm encountering this because I'm using CTRL+C/CTRL+V/CTRL+X operations while highlighting things with a mouse and it started popping up a lot; I then took a moment to narrow it down to the most minimal repro I could find. CTRL+move mouse (hover?).

I did disable "Qb64: Is Hover Text File Enabled" and am still getting this happening (meaning, no difference in behavior).
