Edit System Specs
Filling this out, at least partially, will save a lot of time. Another advantage is when posting a new problem, the person answering can just click the My System Specs link in the bottom of your post. No need to search for the information.
If you have multiple systems just indicate that in the System Specs so that we know why many of the fields are blank.

as to your particular issue, it sounds like the programmer used OwnerDraw in the program window caption bar and message boxes. I don't recall any way of displaying superscripts in standard MessageBox windows functions without using OwnerDraw. Someone else may have run into it and perhaps they will respond. It's difficult to say because often when programmers want features not available in a standard MessageBox, they will either "subclass" it, or create just a Gui with buttons that looks like a MessageBox but is really just a window form. That way just about anything may be drawn on it.
All I can suggest is the basic diagnostics "one of these things is not like the others" and see if there's a difference in OS or 32 bit vs 64 bit. If others are using code pages etc..
