This helped me a lot. Thanks Thread. This is how I make it and solved the problem: To resolve this problem, proceed as follows:
Assure you are the Owner (Mac OS X 10.4 and earlier) and have Access (Mac OS X 10.4 and earlier) or Privilege (Mac OS X 10.5 and later) of Read & Write on your Home folder:
In Finder, press the Command-Shift-H keyboard shortcut. A Finder window opens showing the contents of your Home folder.
Press the Command+I keyboard shortcut. The Info window for your Home folder opens.
Select the Info window.
Open the disclosure triangle for the Ownership & Permissions panel (Mac OS X 10.4 and earlier) or the Sharing & Permissions panel (Mac OS X 10.5 and later) in the Info window.
If using Mac OS X 10.4 or earlier, open the disclosure triangle for the Details panel within the Ownership & Permissions panel.
If you are not listed as Owner (Mac OS X 10.4 and earlier) or under Name (Mac OS X 10.5 or later) or do not have either Access (Mac OS X 10.4 and earlier) or Privilege (Mac OS X 10.5 and later) of Read & Write, then correct these issues using the instructions in the "Setting Permissions" Mac Help document corresponding to the version of Mac OS X you are using.
Warning: When using the instructions in the Mac Help document, do not use the Apply to enclosed items option, if available.
Note: Users of Mac OS X 10.5 or later can start up from their Mac OS X Install DVD and use the Reset Home Directory Permissions and ACLs function of the Reset Password function of the Utilities menu.
Close the Info window.
Try to place objects in the Trash. If so, the problem is solved: stop here.
