Some files (e.g. \windows\system32\drivers\etc\hosts) need to be edited using "run as administrator" with UAC turned on - fair enough. However, it appears that they cannot accept dropped files in this state (yet curiously file paths can be copied and pasted into the open dialogue). I fail to see how this "protects" me from anything - the exact same actions are being performed with the exact same data, it's just that more steps need to be gone through to perform them. Is there a way for e.g. notepad (or another editor) to only ask for elevated priveleges at the time that it writes, rather than reads data? That would both eliminate the extra work required and the arguable "security hole" that exists now.
