NHR issue

All, I'm having some issues with NHR or other personally rolled loginhooks to deal with Office performance. Both result in Word (Excel works fine) error-ing on saving with a "word cannot complete the save due to a file permission error". Then it shows the temp file on the desktop (which is promptly deleted after quiting word). Has anyone seen this? I haven't been able to find anything on google, or afp548 describing this issue. I've played with twiddling the permissions on the directories that NHR sets up, but to no avail. This issue presents itself in both a fully updated Office X, and Office 2004. Thanks!
