If I resize my Sublime window, the code on the line where I’ve clicked the outer boundary of the window gets selected. There seems to be no distinction in the cursor detection between clicking inside the code and clicking outside the code. So, each time I resize, I then get a bunch of selected text as soon as I move my cursor again. If I don’t remember to overcompensate for this strange behaviour and start typing, I end up overwriting my code and have to undo. This is superbly annoying.
I’m using Sublime 3 on a Mac with Sierra OSX.
