Problems with common databaseaccess

I had programming a Delphi-Program (Delphi-Version 1.01) Net.exe, which runs
in Novell Network 3.12.
Net.exe is installed on two workstations and the common Database (Paradox
5.0) is on the server.
If I access on the common Databasetable at the same time from both
workstations, but not the same
databaserecord, I get following message (a white window) on one workstation:
             Systemerror
The file was already open from another program.
Finish this program and repeat.
      Cancel       repeat

If the other workstation had finished the databaseaccess, I click the button
repeat and my program runs correctly again.

The property exclusive from all databasetables is false, so that it should
be possible to access on different records in the same databastable from
both workstations at the same time.

What is the cause of this message?
Who sends this message?
How can I prevent or handle this message this message?

If my program runs in a Novell Network 4.11, I get no message.
If my program runs in a Windows 95- or Windows-NT-Network, I get the same
message as in Novell 3.12.

Thanks

JοΏ½rgen
