Invalid data file problem on network

Hello Everyone,

I have a Clarion 5.5 program that works fine on single computer
(server), but when I try to run it from another network station, I get
"Invalid Data File" error. It's a
Windows XP Pro network, about 10 computers.
I found a solution (not very good one) - when the program is active on
server, it works on workstations also!
I guess the thing is that files must be already open before I try to
access them over the network.
Any help would be greatly appreciated.

Thank you in advance

Are any of the computers involved hyper-threaded machines?  and are you
using TPS files?  If so, we had similar problems in that threads were
being split between the two processors and we were getting file errors.
One way to test is to disable the multi-processor option and try
again.

If it runs okay, then you need to bind the program to one processor.
There's an easy to use template that solved our problems:

binder template).  Also, double check that your files are all set to
'Share' in the Global Properties, File Control tab.
