BUG - NOD deletes attachments, if sending mail via "right mouseclick" -> "send to"

Hi,

I'm using Vista Ultimate with Outlook 2007, all updates. There might be a bug in NOD32 V3 RC1. If i'm sending an email via right mouseclick -> send to -> Mail recipient, the attachment will be deleted, if cleaning Level ist set to 1 or 2. I tested it with sending myself an email und check the mail not with outlook 2007 on my pc, but with gmx web access (email stays on gmx email server). Exceptions:

1. Sending an email via outlook 2007 -> new email -> insert attachment -> send -> no problem
2. Sending an email via right mouseclick -> send to -> mail recipient AND the recipient is also using outlook 2007
3. Cleaning Level in Nod32 email protection is set to 0.

Any ideas how to resolve or is it a known bug?

greets, leschy
