Weird (but reproducible) screen display glitch: \[ImaginaryI] appears as just "i"

The weird behavior is that when I run the following inputs the
"\[ImaginaryI]" character associated with the "I (g/h^2)" in Input[2]
displays inside the Sqrt symbol in Output[2] as the expected Mathematica
"ii" symbol that looks like two lower case i's squished together under a
single dot -- but the same character in the same place (under the
radical) in Output[3] appears only as (what sure seems to be) a
**single** lower-case "i" -- while the "I k" terms in Input[3] display
with the proper \[ImaginaryI] character.
In[1]:=x;Remove["Global`*"];
In[2]:=f= Sqrt[1+I (g/h^2)]
Out[2]=\!\(\@\(1 + \(\[ImaginaryI]\ g\)\/h\^2\)\)
In[3]:=rho=(-f+I k)/(f+I k)
Out[3]=\!\(\(\(-\@\(1 + \(\[ImaginaryI]\ g\)\/h\^2\)\) + \[ImaginaryI]\
k\)\/\(\@\(1 \+ \(\[ImaginaryI]\ g\)\/h\^2\) + \[ImaginaryI]\ k\)\)
This is at least semi-reproducible: It remained when I copied the
offending lines from the place where I had first noticed it (where I was
using symbols other than f, g, h) and pasted them into a new notebook.
It remained when I re-typed the new example shown here into a fresh
notebook. **It goes away if I just use "I g" instead of "I (g/h^2)" in
Input[2] -- and comes back when I restore the "/h^2".** It remained
after shutting down Mathematica and re-opening it.
Oh, and if I use the FrontEnd "Copy Output from Above" menu command just
below Output[3], the Input[4] that is created displays properly -- **but
if I execute it the Output[4] is again wrong**.
A font problem of some sort, maybe?
