>Arnon! Thank you for respond. Do you know what bugs they fixed. And if I have this Sp3, must I upgrade my VFP, should I, or it's kind of it will be better to do it.

MS had a list of 60+ bugs they fixed from 5.0 to 5.0a
I didn't look but they may have a list of fixes for the SP3 build as well
check the MS KB
