This a known issue that occurs when the Launcher is open on the remote machine. The only workaround is to close the Launcher using the Command-W key combination. You should avoid having the Launcher open on remote workstations.
If the workstation is running Mac OS 8.5 or later, you can use the following steps to mimic the Launcher's functionality:
1. Create a new folder and open it.
2. Go to the View menu and choose "as Buttons".
3. Place aliases to the desired items in this folder. To duplicate your current Launcher setup, drag in the contents of the Launcher Items folder which resides in the System Folder.
4. If desired, drag the folder to the bottom of the screen so that it becomes a pop-up window.
