Powerpoint 2007 send via email bug?

Hi All

I have run across an issue with office 2007

1 configue office 2007 to send email via lotus notes

2 create a powerpoint presentation and save as pres1.pptx

3 click the office button\send\email

4 a message is created in lotus notes and the file has been attached.

However the filename has a ramdomly generated name instead of pres1.pptx

This does not occur in word or excel.

Can anyone confirm this is happening to them?

Cheers

Tim
