Yes.  E.g. in <http://www.hobbyecke-pc.de/images/screensh2.png> the
text says:

|   wä wö mä mö
| In the letters "w" and "m", the right column of pixels is not
| displayed.
|   wa wo ma mo

If the iso-characters "ä" and "ö" are replaced by their ASCII
"counterparts" ("a" and "o") the letters "w" and "m" are displayed

Joachim, does turning of "ClearType" solve the problem?

Bye, Reiner.
