comments copied successfully

Dear community
Now and then a small window comes up with “comments copied successfully” rightly says “comments copied successfully” due Danish system. The pane is on top of everything else and can not be moved or deleted, but disappears when Scrivener shuts down, does anyone have an idea for a solution to the problem.

I cannot think of anything along those lines that may be coming from Scrivener, but perhaps if you could take a screenshot of the alert it would be easier to tell what is going on.
