Have you seen all the posts about Norton AntiVirus Try disabling it if you have it.
This is a post from John Elliot
There is one known problem that will cause Inventor to run REAL SLOW.
- Windows XP
- International version of Inventor R6
- Corporate version of Norton anti-virus V 7.61.935 with file checking
enabled.
This causes the task, winlogon, to start gobbling up all free CPU cycles as
soon as Inventor starts.
Workaround: disable file checking or upgrade to a newer version of Norton.
This is documented in the readme.
