Microsoft Graph version 3.0b, which ships with version 3.0 of Microsoft
PowerPoint for Windows, requires the MS Sans Serif screen font to
properly display rotated text in the Format Text dialog box. Under
some circumstances if you choose Text from the Format menu in
Microsoft Graph, the text boxes in the Orientation section of the
Format Text dialog may appear as empty rectangles.
- Verify that the MS Sans Serif font is installed:
   a. Open Control Panel and choose the Fonts icon.
 
   b. Highlight the MS Sans Serif entry on the list of installed
       fonts.
 
   c. If a font sample does not appear, or if the MS Sans Serif entry
       is missing entirely, choose the Add button.
 
   d. In the Add Fonts dialog box, go to the WINDOWS\SYSTEM directory.
 
   e. A list of available fonts will appear. Choose MS Sans Serif and
       choose the OK button.
 
   f. Highlight the MS Sans Serif entry again to verify that a font
       sample displays.
 
- Check the [FontSubstitutes] section of WIN.INI. There must be a
   line in this section that reads as follows:
       Helv=MS Sans Serif
 
   If this is not correct, correct or add this line, save the WIN.INI
   file and restart Windows.
 
- Verify the integrity of the MS Sans Serif font by using Character
   Map:
   a. Run Character Map.
 
   b. From the fonts list field, select MS Sans Serif.
 
   c. Verify that characters are showing up in the Character Map
       matrix.
 
   Using Control Panel to check the sample display of a font may not
   correctly identify a corrupted font. The Fonts display may map to
   another font incorrectly which will make a corrupt font appear
   to be correct.
 
- Check the Fonts section of Control Panel to see if a third party
   TrueType font package containing a Helv font has been added to
   the Windows environment. If you see that a Helv TrueType font has
   been added, perform the following steps:
   a. Open Control Panel and choose the Fonts icon.
 
   b. Highlight the Helv entry on the list of installed fonts.
   c. Choose the Remove Fonts button.
 
   d. In the Remove Fonts dialog box, clear the check box labeled
       Delete Font File from Disk.
