If you're talking about [plain] Text, and not Dimensions that create their own stacked fractions, nor automatically-stacked fractions in Mtext [though this could be the issue in Mtext not via its stacking capability], that sounds like a potential text-font issue.  Is the font involved one that does not come with AutoCAD?

 

I have seen text fonts in which certain stacked fractions are defined as single characters, with special-character numbers for using them.  If you've changed it to a different font, or if that specialized font is not present and AutoCAD substitutes something else, those special characters will not be recognized, and the question mark will be used in their place.  When you say "the next time the drawing is opened," does that apply when it's opened on a different computer than one on which they showed correctly?  If the problem is restricted to certain computers and does not occur on others, they may just be missing the font.

 

One way to check [whether or not on a computer where the problem occurs] is to look at the text content as AutoCAD stores it, not as it displays it.  Type in:

 

(entget (car (entsel "\nSelect problem text: ")))

 

And look at the resulting entity data list.  There will be an entry like this:

 

(1 . "Text content here")

 

What does that contain in a problem Text object?
