Formatting disappeared in Domino Web Access message

Hello,

we have a strange behavior on some Domino Web Access clients.

When a user writes a new memo the stored and received message has no formatting at all and no line breaks.

We have a Lotus Domino Server 7.0.1FP1 on Linux, Windows SP SP2 with latest patches and use IE as browser. The template of users mail file is DWA7 (dwa7.ntf).

Other users with the same environment could send formatted messages. Any hints?

Thanks in advange

Andreas
