I have been using Onenote succesfully for about 3 weeks on crossover (Mac), but since new year the app was no longer able to create any new tabs, folders, notebooks, etc. I reset perms on all of my notebooks to by everyone R/W. Today the app started prompting at opening that it wasn't installed for this user. I dropped the bottle and are trying again. I have had several random Crossover crashes as well while working with the bottles, and attempting to delete this non-functional app.
