Zoom level keeps resetting

This is a pretty minor thing, but it does get a bit irritating - every time I open a previously saved Scrivener file, the zoom resets itself to 130% - rather large for my tastes. I know it only takes a second to fix, but if there’s a fix for this, I’d prefer to use that than keep on fixing it each time.

This is a fairly recent development - I couldn’t pinpoint exactly when it stopped retaining the zoom level (since the first few times I had to fix it I barely noticed - until all those added up to the irritating point), just that it used to save it just fine.

Thanks in advance guys (even if the answer is “grin and bear it”)
