  * The line thickness was too large when printed under Windows 98 SE and ME.
  * TrueType fonts didn't appear immediately inside the plug-in (a substitution font was used), one had to cause a window refresh to make them show up.
- It is no longer necessary to set the decimal separator as dot to produce valid documents.
