If you try to read an email message with many long lines in any of the Solaris 9 12/03 Unicode or UTF-8 locales, CDE Mailer (dtmail) appears to hang. The message does not display immediately.
Workaround: Choose one of the following workarounds:
Enlarge the dtmail Mailbox window to accommodate 132 columns.
Disable the Complex Text Layout feature by following these steps:
Change directories to your system's locale directory.
# cd /usr/lib/locale/locale-name
In the previous example, locale-name refers to the name of your system's Solaris 9 12/03 Unicode or UTF-8 locale.
Rename the locale layout engine category.
# mv LO_LTYPE LO_LTYPE-
Rename the category for the locale layout engine to the original name (LO_LTYPE) before you apply any patches to the locale layout engine.
