Permissions problem

Strange issue today when trying to install updates to Notebook and Onyx on my 2011 imac running 10.7.2. *I never had this issue before today. *I run my user account as a standard user, so when i drag any application over to my applications folder, i have to authenticate. *Today, when dragging over the new version of Notebook or Oynx, when i selected replace the current file and authenticated i received a notification entitled "copy" This cant be completed because some items needed to be skipped.....please goto get info and make sure "locked" is deselected and check sharing and permissions. *I did so and everything was unlocked and looked ok. *Still not working. *Strange thing was if i completely uninstalled the application, and then dragged the new version over, authenticated, that worked fine. *So I then repaired permissions......still didn't work when i just wanted to copy it over. *Next i reset ACLs on the user account from the lion recovery partition......still the same result. *I checked around on google, didn't find much more than terminal commands to reset ACL, which didn't work for me. *Lastly, i called Apple. *They told me to change the privilege of everyone (previous to the image below it was Read Only) to read and write and to check the "apply to enclosed items"on my Applications folder....which i did. *That worked....BUT the issue is i am no longer prompted for my admin username and password when moving stuff into my applications folder which i kinda liked. *Also, seeing how this all just worked before when the everyone setting was read only, I'm concerned that the Apple reps answer was also a kind of work around and that there might be an underlying issue that we both are missing. *Any suggestions would be appreciated so that i can be prompted for admin user/password again

 

Would that be the same as running a reset acl via the terminal in the lion recovery partition ?
