I have a user who is losing her bottom favorite in her bookmark list using Internet Explorer 10. She keeps having to readd it. It doesn't matter what the favorite is.. It's always the bottom one. Is there anything to explain this? I'm sure there is but I am at a loss!
What is she doing between the time of adding the favorite and losing it?
Install IE 11.
If that does not help, create an unwanted favorite so it can be at the bottom.
