Now, you're confusing me. Are you saying that the new user account does't exhibit the problem? The easiest way to do that is to use the new user's drop box:
*To give a file to another user on your computer:*
+Open the user’s Public folder (in their home folder in the Users folder on your hard disk).+
+Hold down the Option key and drag the file to the Drop Box in the user’s Public folder.+
BTW, no one from Apple routinely reads these posts. These are user-to-user forums.
If you want to report this issue to Apple's engineering, send a bug report or an enhancement request via its Bug Reporter system. To do this, join the
Mac Developer Program—it's free and available for all Mac users and gets you a look at some development software. Since you already have an Apple username/ID, use that. Once a member, go to
Apple BugReporter and file your bug report or enhancement request. The nice thing with this procedure is that you get a response and a follow-up number; thus, starting a dialog with engineering.
