Bizarre phenomenon

	I edited, ran, and saved a file "Separate-New.nb" containing
the following code segment.

nn = 5;
makmota;   
ptab = {0, 0, 0, 0};
qtab = {3, 4, 4, 3};
rtab = {0, 2, 3, 4};
stab = {3, 2, 3, 1};  
qloop;

	This code worked. But when I closed Mathematica, restarted it, and
opened a supporting file and then Separate-New.nb, the word "qloop"
mysteriously had something almost  invisible between the q and the l.
The same thing happened in a very similar line below this one, but not
on a third very similar line.. These three function names are in
boldface and highlighted in green. The only visible symptom on the
screen is a larger than usual "space" on at least one side of the "l"
or maybe both, but the cursor steps over it normally and does not
indicate an actual  space character on either side. When I erase the
word qloop and retype it, everything immediately works.
	I have this phenomenon happen almost regularly. I posted a
question about it months ago but no one answered. I am 98% sure that
the "space" was not there when I saved the file.
	Any tips? Thank you.
