Yes, i can see the issue you are reporting.
In the webassist/email folder there should be a file named waus_(the page name).php. If you open that page and look for this line of code:
$WA_MailObject = WAUE_SendMail($WA_MailObject,$MailAttachments,$MailBCC,$MailCC,$MailTo,$MailImportance,$MailFrom,$MailSubject,$MailBody,"waue_untitled_1");
and change it by updating $MailBody to stripslashes($MailBody)
This is a temporary work around. I will log a bug in our bug base and a fix will be included in the next dot release.
