When sending an email in HTML format the message contains all "k"s
 

I have a VERY strange issue. Using Outlook 2007. If my mail format is set
to HTML and I send an email message it replaces the body of the email with a
bunch of k's

for example:
Body: Hey man what's up?

What gets sent in body:
kkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkk kkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkk kkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkk kkkkkkkkkk

Now this only happens when set to HTML format. I changed the default to Rich
Text but if someone sends me an email in HTML format and I reply (it keeps
their HTML format) and it sends all k's again.. I have to mnually witch the
format for replies which I sometimes forget to do. Anyone have this happen
to
them or know of a way to fix it?????
