This morning when I started work on a project, I noticed that my notes and dimensions were being displayed in odd characters which I have never seen before. So I checked my system settings and all of my font settings have been changed to 'Marlett'. I didn't change these settings. I have always used 'SPhand' as my font. However, after I set the fonts to SPhand and went back to my drawing, all of my text and dimensions were no longer visible but they were there when I placed my edit cursor in the location of the note and selected it. What happen and how do I fix this?
