[R-SIG-Mac] R.app not handling events

[John Fox]

Dear J.,

What you report is, I believe, a different issue. See 10.3 in the R for 
macOS FAQ.

Best,

I can't scroll the console to look at earlier results, and I don't see partial results until the whole computation is complete.  If I ask MacOS to switch to that window, it won't come to the top (though clicking on it does bring it up, but I need to be able to see part of it to do that).
