a new version just popped up on my MacBook

I have been playing Uni Sudoku for quite a while and it is one of my favorite games. A few minutes ago, I opened it and saw a new interface. Unfortunately, the new display is exceedingly large on the MacBook. I have to back away from the screen to view it. Also, the image is so large that I can no longer make a quick scan of it to see which numbers are needed here and there.

Ross strikes again. The last time a new upgrade fiddled with the user interface (on the iPhone), users complained to such an extent that the version was withdrawn and reverted to the original interface.

I did not choose this upgrade; it automatically appeared. How can I get rid of it; in other words, can I revert to the previous version?

Love But Requesting Fixes

Older versions of this app worked great for me but the latest version running on Yosemite is buggy. Once in a while a square will be unfillable but there’s no way of knowing this except during a game. Would like an option so the SAVE prompt doesn’t pop up each time - it lags quite a bit before opening). Also would love to see an option for resizing the window. Last request would be to add a pause button on the timer. Otherwise, love the app.

Save As is gone

I like to save stages of my solution so I can backtrack if necessary. This is probably cheating but it works for me. This version lacks a Save As selection.

I tried to go back to 2.0 but something has changed. if you double click a number the same number in the row or column is not removed.
