Printing in Vista with UAC enabled

Question

I am running Acrobat 8.1.2 on Vista Ultimate SP1 with UAC enabled. My account is a member of the Administrators group.
When I open IE and try to print to "Adobe PDF", Adobe properly shows me the "Save PDF File As" dialog where I enter a valid filename. The save path shown is the "User -> Documents" folder (where I have proper file rights). When I click Save to save the PDF, a dialog shows up which says "For your computer's security, this file was saved to the Temporary Internet Files Folder. Do you want to open this folder?"
If you reply yes, it opens Explorer to a path where the PDF does not exist. I cannot find the PDF anywhere on my system.
My research on Google has resulted in comments which claim that this issue was resolved in Acrobat 8.1. Yet, I still have the problem.
If I set IE to "Run as Administator", the problem does not happen. But then I lose all the security benefits of UAC in IE.
Is there a way to fix this problem without disabling UAC or without disabling Protected Mode is IE which again helps protect my computer?
TIA,
Pierre

Answer 1

I'd like to report the exact same problem (I'm using Vista Business, SP1, UAC enabled) and add: 
-- the problem persists after a complete reinstall of Vista (up to SP1 and all updates) then a clean install of CS3 Design Premium
-- Clicking on the Adobe convert button in IE7 seemingly works since something pops up in Acrobat but the file is actually distorted.
-- If I open IE7 using "Run as Adminstrator" the problem goes away. I also have no problem using print to pdf in other programs (Firefox, MS Office, etc.)
-- the above problem plus the event error below are hardware dependent:  I have them on my Dell Optiplex 755 desktop (hard drives in ACHI/SATA mode) but not on my Vista SP1 Thinkpad laptop.
-- With Flexnet Licensing running, I also get 1 to 3 Event ID error#'s 1108 EVERY TIME I shutdown the computer (see your Event Viewer/Custom Views/Administrative Events):
"The event logging service encountered an error while processing an incoming event published from Microsoft-Windows-Security-Auditing."
