I'm just after some advice please. I am an academic editor and use Word 2016 professionally. I use track changes for every document. However, I have found that in many cases - probably 75% - I will be working on a document and the cursor will suddenly jump to the last page. This is incredibly annoying. I have discovered that this doesn't happen when I set it to 'view all markup', but I can't edit very easily when I can see all the changes so this is not an appropriate solution. Please note this is NOT the same issue that other users have had with the cursor jumping to the end after pressing 'enter' - that can be fixed in Page Setup and is not the same problem I am experiencing.
Another issue which may or may not be related is that the 'save as' box will also randomly pop up. I am definitely not accidentally pressing the shortcut as it happens when I'm typing or just when moving the cursor along the text using the arrow keys.
This has been happening for around a year now and at first I thought it was a bug that would be patched in later updates, but this hasn't happened. I have repaired the program with no success. Any advice would be most appreciated!
