Zimbra cuts off email message when forwarding

[ple]

Hi,
The recent upgrade to 6.0.14 has introduced a different issue. When users forward an email to another email account located on the same server using Web based client, the bottom of the message gets cut off about 1/3 of an original message. It appears to be OK if we switch the setting to forward as an attachment instead of forward using "Include Original Message". Does anyone know what's going on and how to fix it?
Thanks in advance,
