It is Start8 that is being affected: that is where the text is becoming blurred. Disabling Start8 is not going to tell me what is causing the problem. However, when I disabled Window Blinds by selecting the default theme, instead of Precision or any other theme, the problem went away. That's why I think there is a conflict and wanted to know whether the participants in the forum could provide a solution, a patch, or a work-around.
I'm going to work on it more and see if there is anything in my Windows 8.1 system that is causing the problem. Thus far, though, I have spent a great deal of time on it because I am really trying to avoid contact with the Metro UI in Windows 8/8.1.
