The following problem just happened twice in a row.
(ST Build 3113 Mac OSX 10.11.5).
I have a file open in one window, and a project open in another
window. I am working on the first window, I switch to the second
window, and I see the first file is cloned in the second window
(without any action of my part - this happened a few times also in the
past but I did not consider it a serious problem until now).
I revert to the first window, and the window is suddenly empty!
The unwanted clone is empty too. The file is still there but it has
zero bytes.
The first time this happened I could recover the file thanks to
the Local History plugin (thank you!). Immediately after, it happened
again, but this time I was more careful. When I saw the empty window
I did an undo (CMD-Z) and the content appeared again.
I’m sorry if the description is lacking but I was caught by surprise.
Has anyone experienced something like that? Maybe this is
due to something I did inadvertently? what might that be?
