Os X asking for admin password to move files from finder to desktop?

[willw77]

I have two accounts a standard user account that I use all of the time and a separate admin account to use when I need to. Okay, so I just started my mac up and was creating some new folders and moving files from my user folder to my desktop (on my standard account). OS 10.5 comes up with a box asking for an admin password to make changes. It also does this when I try to move files to the trash. How do I fix this permissions error?

I've done that, it didn't work.
