Window layout problems after update

[Reinier van Rooyen]

@domwesker I know it’s a year later, but if I found this in a google search so can someone else. I just want to confirm the later replies here. This problem seem to stem from using Slack. In my case I had the go into task manager and stop ALL(sort by name since they tend to play hide and seek) Slack processes. Then simply close NP++ and re-open.
