This problem is occurring with Adobe Acrobat Pro DC. When I am in a PDF and I have the pages tab open the pages tab will all of a sudden close on its own. This is not a isolated event. This happens multiple times a day with many different PDFs I am working with.
Has this happened to anyone? I have tried uninstalling and repairing the program and neither of these have helped.
I have not had this issue happen, but it is possible that the F4 key gets tapped (maybe accidentally), which will toggle the Navigation Panels open and closed with each press.
If I find any other causes mentioned, I'll chime back in.
