Thank you for your replies. It's great to see you take such a proactive, enthusiastic stance with both the technology and your customers.
On another note, I ran into a behavior I'm not so sure is a bug but rather just misleading. I created a folder on the desktop and then later tried to rename it. I received three prompts including a UAC prompt. Finally, the rename failed. I was logged in as admin and had adequate permissions. After a google or two, I realized I had a word doc open that was in the folder. I closed the documents and renamed the folder without any prompts. In other words, the interaction I had with the system gave me the impression it was a security restriction of some kind and nothing about open file or anything of that sort. I know this may not be in your area but the access denied and UAC prompt was confusing. In XP it's real clear: "close down any open programs."
For what it's worth . . .
