OperaII 6.8x email hangs

Has anyone come across any issues with sending emails mainly out of SOP where it just seems to hang, if we crash opera and go back in emails fine the second time. This is happeneing on same site with a mixture of XP Office 2003 and win 7 Office 2007.

Seems to be more on the emails where they type a longer message in the body text whilst on the publisher screen.
