I don't think this is an issue with VFP 8 itself, but something related to what you're doing with the data.
Possibly you have failures or maybe you're using PHP on those tables?

>I'm just curious to know if SP1 is resolving the corrupted index problem. Since VFP 8, sometimes, once every two or three months approx., I get a message that I have a corrupted index. When I have this, even if it doesn't bother the execution of the application, I do however recreate the tag. I have experienced that four times in less than a few months. I got it today as well. SP1 has been installed on the server after that. So, does someone know if that has been taken care or if it is better?
