I think you need to share your code otherwise we can not help you fixing
your problem.
Are you using the RAND() function?

btw: please post to a single newsgroup instead of posting the same question
in multiple groups. Most people here read all groups so you'll probably
always get an answer.

Are you using Rand(-1) before getting your numbers?

From the fox-help:

"If nSeedValue is negative the first time you issued RAND( ), a seed =
value from the system clock is used. To achieve the most random sequence =
of numbers, issue RAND( ) initially with a negative argument and then =
issue RAND( ) without an argument. "
"If you omit nSeedValue, RAND( ) uses a default seed value of 100,001."

Hi Finns:

Try compiling this code into a simple executable and see if it works:

I hope this helps.

Finns,

The set of calls to rand() in every VFP session will return the same
sequence of psuedorandom numbers. This is actually a good thing, it allows
repeatability so that you can reliably test code that uses random numbers.

You are seeing different results between your dev time and the runtime
because you've been making calls to rand() all along.

As George posted include a rand(-1) call at the beginning of your prg to
randomize the starting point of the sequence.
