I've also had this issue - and I also had "Save & New" as the default...so:

• why did it change, and
• why is there no ability for the user to change the default?

Sorry to say, this change was clearly made without thinking about the user.

Clearing the cache and CTRL+ALT+S are really work-arounds for a function that just doesn't work as efficiently as it should - or, as it USED TO!

Please bring this to someone's attention so it can be improved.

Thanks!
