Client File Secuity (Citrix and Vista)

This is not critical by any means but has become quite an annoyance here as there are dozens of Help Desk calls coming in on this issue.

Here is what seems to be happening. We just migrated from XP to Vista on the desktop, and ever since this occurred we have been having some issues with our Citrix users in our remote offices.

When users are in any application using Citrix (we will use Outlook for this example) and they go to attach a file to a the Citrix Client File Security box pops up and says the following:

[A Server or application is requesting access to your local client file.

What Access would you like to grant?]

I understand this is normal, unless it happens every single time you log into Citrix and attempt to access files on your local drives...

The setting for "Full Access" and "Never ask me again" means that from that point on Citrix should never ask you again (the way it worked in XP!).

In Vista choosing this doesn't help, the next time you login to Citrix it asks again, and again, and again... Etc

As I stated this is not critical, but it's flooding the Help Desk with calls and now they are coming to me :S

I'm sure this has something to do with Vista's security, especially since the users don't have local admin rights.

I ran Process Monitor trying to see where this writes to the registry but that really didn't help me. I have change IE7 security settings but nothing seems to work.

Any ideas?
