Word 2003 Hangs on Opening using 100% CPU for 3 to 4 Seconds

[Net]

Hi all,

When I open a document in Word 2003, the program hangs for 3 to 4 seconds
and uses 100% CPU.

The document displays quickly, but the hourglass stays and the PC locks up
for 3 to 4 seconds.

I have checked the usual, like file paths and startup folder, and even
re-installed Office, but with no luck.

Anyone got any bright ideas?

Thanks.
