The application cannot find a file while a PC Card is inserted.
Some PC Cards when inserted in a computer that is connected to the docking station may change the drive letters of the
disk drives in the docking station. If this occurs, an application you are using may not be able to find files.
To correct this condition perform one of the following steps:
 Remove the PC Card, and restart your computer. Do not insert the PC Card while using that application.
 Change the drive letters of the disk drives of the docking station or of the PC Card. Refer to the Windows ® help files
or the application manuals to change the drive letters.
