Win7 x64/Admin here

I am running Win 7 Pro 64-bit with an admin level account.-lanux128
Sorry about chopping this up so much, but minutia can be really important with this kind of stuff.
So you are logged in with an account that is a member of the local administrators group (which would include Domain Admins)... Yes?
At times I would drag a url shortcut from the desktop on to the browser window but the action would fail silently, causing much frustration.-lanux128
I can't honestly say I've ever tried doing that. But I did try it just now and received a would you like to save or open link prompt from IE.
I have to exit the browser and relaunch in admin mode for the drag-n-drop to be successful. the same goes if i am trying to interact between an explorer window and totalcmd window.-lanux128
Okay, this part is starting to make sense, if you are running an alternate shell as admin it's not supposed to work because DnD does not work between sessions. I frequently trip myself up with this when editing system files. If I run notepad as admin, then drag a file from desktop/explorer and drop it in notepad, nothing will happen because they're both in separate sessions.
my uac setting is at default so why do the apps lapse into non-admin mode? does anyone else experience this situation?

Even domain administrator accounts (and their shell's) run with restricted user level permissions when UAC is enabled. So any system level changes require selecting run as admin or clicking yes/ok on a UAC prompt at some point. So if something is being run as admin it will be in a different session and therefore not available to interact directly with other non elevated applications.
