After we upgraded to BB 2016, the default app for PDF has changed every couple weeks from BB to Edge on our Windows 10 machines and XPS viewer on our windows 8.1 machines.
I this a windows thing or something going on with BB that changes the settings? Kind of annoying when we don't realize its switched and edge tries to open a 400mb 100 sheet drawing set and locks the entire machine while attempting it. We are able to change it back but it keeps resetting.
Note this never happened on BB 2015 on W10 or W8.1
