Report an app problem

Tell us what you were doing, what happened, and whether it happens every time or happened once — that is the fastest way to find it.

A screenshot of the problem, attached below, is the quickest way for us to see it. Please do not send your documents or their contents. Recording, comparison and restore happen only on your computer and we have never had those files, so they would not help us. If it matters, the kind of file (a Word document, say) and its size are enough.
