Bug introduced in V10.0 and resolved in V11.3

(These are guesses. It is likely to have been resolved in an earlier version V11.X, but V11.3 is what I have access to.)


I am running Mathematica 10.0.1 on a four-year old iMac running OS 10.6.8. The following irritating behavior occurs regularly: I have a list with parentheses, and later on I need to add something to an earlier part of the list that involves quotation marks. As soon as I include the quotation marks, the matching between the parentheses gets lost, and I need to go in by hand to fix the parentheses matching. See the gif below for an example.

This also happens in version 10.0.2.0 on a 2014 MacBook Air running OS 10.10.4. I have verified that this does not happen in Mathematica 8 on the four-year old iMac.

Is this problem reproducible in general? How do we fix it? Is it already fixed in a later version? If so, is there a work-around without upgrading? Should this be reported as a bug to WRI?

    $\begingroup$ Yes, I see the same behavior in 10.2 on Win7-64. Interestingly, the behavior seems triggered by two-dimensional formatting of the power on my system: if I write (a+1)^2 instead of using the superscript form, the parenthesis matching seems unaffected by quotes. Is that true on on your system as well? $\endgroup$

  • $\begingroup$ @MarcoB. Yes, that's true on mine. I've also run into situations where the matching between a Slot and the corresponding & will get lost, but I wasn't able to reproduce that; I can't quite remember when that happens. $\endgroup$

  • $\begingroup$ I remember another question about a similar problem, but not well enough to find it. Can anyone else do better? $\endgroup$

    $\begingroup$ @Mr.Wizard. This one, I think. It's essentially the same problem. Mark as duplicate? That one is still unanswered. $\endgroup$
