I have a "strange" issue - has anyone any ideas.

Windows Vista
Word 2007 (same applies for other programs)
Thurerbird 3

Now - I prepared a Word document - and in Word selected Send as pdf -
the attachment opened up Thurerbird as it should,

Three days later - I adjusted the Word document - and again seelcted
Send as pdf - sent email.

When I looked - Thunderbird had sent the "old" document and not the
new one.

since then I have tried various things - such as saving before send
etc. The only workaround is to delte the "old" pdf or to save as pdf
and then send.
