What conflicts have you found to be present, if any, between default windows 7 security settings and the Novell Client (IR7)? Have you had to tweak UAC settings or IE9 security settings in order to achieve reliable file read/write performance, mapped drive reliability, etc?

Have you had issues with copying files to a system protected Program Files or Windows directory from a mapped Novell NCP/NSS network drive? Does UAC get in your way and prevent a direct copy even after authorizing the copy?
