There are two related Finder copying bugs still present in Leopard as of 10.5.5; I doubt the issues have been fixed in 10.5.6. I don't know when they were introduced. Here is how to reproduce them:
1. Go to a folder you don't have write privileges for (like the global /Applications folder if you're a non-admin);
2. Find a file you want to update. (Act like you've just downloaded an update to a common application);
3. Drag the file to the folder so that the Finder prompts you to authenticate with your admin login;
4. After authenticating, the Finder will start to copy the file and then will stop with a dialog asking if you want to replace the already existing file with the same name;
5. Click replace.
Do that and then you'll get a dialog that says you don't have sufficient privileges to complete the command (even though you just authenticated). But here's the best part - look at the existing file you were going to overwrite. It's still there, but if you look closely you'll see that it is now zero bytes! The Finder started overwriting the file but didn't finish. It erased the existing copy and failed to put in the one you wanted to overwrite it with. This is actually two bad bugs in one. This is really only noticeable to those of us who don't run as admin all the time. It has happened to me a couple of times now. Good job, Apple software QA.

Maybe you should try that on 10.5.6? I just did, and it seemed to work.

Okay, that's a good idea.

It makes no difference if you use 10.5.6. The bug is still there and happens for a large number of the app updates I perform, but not all. I'm not 100% sure if this is the case but I believe it is more likely to happen with apps that are signed (or whatever it is that was introduced in 10.5).

P.S. If you then repeat the copy, you are asked if you want to replace a newer version of the file rather than an older one as before.

I just trash the original when I hit an "insufficient privileges" warning. Why? Because half the time the POS doesn't even ask me to authenticate.

What happens if it's just a sudo mv command from Terminal? That should work as an annoying but usable workaround. Would be very interesting if it had the same error/bug as Finder.

Okay, I'm now running 10.5.6, and at first I thought it was fixed but it definitely is not. This time I tried replacing an older version of GraphicConverter with the current version. Instead of completely overwriting the file with nothing, it took the size of it from ~56MB to 28MB. For all its brilliance, Apple's QC does often lack. I am going to start sending this thread to Apple feedback once a week, whatever good that will do.
