My brother is running a computer with XP HE SP2, fully updated.

In OE6, despite being set to receive and send mail in HTML format, the
messages are displayed in plain text; however, when clicking on 'reply', the
messages then revert to HTML.

Re-setting via OE's options makes no difference - it will not retain the
setting, and pressing alt+shift+H, only works for the message which is
displayed at the time.

He had OE Quotefix installed, we uninstalled it to see if that was the
cause, but to no avail - it's just the same.

Is there a fix or tweak available, please?

Thank you,
Jean
