Couldn't save; currently locked by user 'Item2' on machine 'Item1'.
You tried to save a record that is currently locked by another user. Wait for the other user to finish working with the record, and then try the operation again.
The MS-DOS file sharing count has been exceeded. You need to increase the number of locks installed with SHARE.EXE.
To load SHARE.EXE
1 Exit Microsoft Windows.
2 Using a text editor, add the following line to your AUTOEXEC.BAT file:
If you don't have an AUTOEXEC.BAT file on your system, enter the preceding line at the command prompt before you start Microsoft Windows. The exact number of locks you use depends on the particular applications you run and the number of files that are locked at any given time. If other applications require file locks, you may need to specify more than 500 locks.
3 If you added SHARE.EXE to your AUTOEXEC.BAT file, reboot your system.
4 Restart Microsoft Windows, and try the operation again.
