Here is an Mtext question: when I double-click on some mtext, it displays the text Formatting box. If you click on the Ruler, this makes a ruler appear above the mtext. At one end of the ruler, there is a double-arrow symbol that - if you double-click on it, makes an existing background mask exactly cover the mtext.
I have been doing a lot of mtext cleanup lately. I have been double-clicking on the double-arrow for a while. The double-arrow symbol has started to "shrink" in size, to the point where it is getting difficult to line up over it to double-click on it.
There does not seem to be any way I can control its size.
What is the solution? Why has it started shrinking anyway?
Correct. I do not see this in 2015, but I also have never noticed it in any earlier version either.
