Citrix Streaming Issue trying to call Microsoft Office causes long delay

Looks like there is a bug using version 6 of the offline plugin causing a 5 minute delay trying to open Microsoft Office from a streamed application.  The issue I speak of presented itself when trying to call Microsoft Word (Either locally or streamed) from within a streamed clinical application.  The clinical application I was working with attempts to open Word to generate a from using Word macros.  I tested the issue with Word installed locally on the XenApp server as well as having Word installed in the streaming profile.  In both scenarios I encountered the 5 minute delay when trying to open Word from within the streamed app. 

I contacted Citrix support to further investigate the problem and was surprised to find that this was an issue known within the Citrix support team, however, has not been released as a KB on support.citrix.com.  The fix is relatively straight forward and only involved changing the HooksMSI DWORD value in the registry to 0.
