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
correctly.

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

Bye, Reiner.
