Hi all: Windows 7 is consistently logging this error:

================================================== ============
Windows detected your registry file is still in use by other applications or services. The file will be unloaded now. The applications or services that hold your registry file may not function properly afterwards.

1 user registry handles leaked from \Registry\User\S-1-5-21-1851032915-2267366586-407016004-8173:

================================================== =============

We are running Windows 7 SP1 64-bit, Novell Client 2 SP3, ZCM client 11.2.4 and iPrint 5.94.
Any ideas what is causing this? How to fix?
