Geez - so R3 is now available with the fix to allow overwriting of backup file. BUT!!
Not that I am complaining, but they implemented it so that when Q sees a backup file of the same name, you get a pop up box that gives you TWO choices - one is to allow overwriting, the other just CANCELS the operation! No option to NOT overwrite but STILL do a backup with a new name. That's going to get some people bummed out since I suspect some folks LIKE having the multiples (indeed, I would like to still have that option perhaps too!).
