I'm the only user, and I've changed the permissions on the desired folders for my user account (not hidden administrator account) to allow
Full control (including Write). I checked the main folder and all sub-folders where I want to download, and all have the permissions. Yet when I try to D/L an image, I still get the "You don't have permission to save to this folder. Do you want to save to the Pictures folder?" When I choose Yes, I get the even stupider "For security reasons the file was saved to the Temporary Internet folder."

[my recollection of these messages]
Now what do I do? I'm using Ancestry.com to D/L census images that I want to look at offline. I only have a month before my paid subscription is up, and I'm wasting time having to try to remember which folder various images go into when I have to move them from the Temporary Internet folder.
TIA for any help.
