Yes, and now I've found out it's not only less performant on 
creating, but also on adding and updating records. My app runs very 
fast on a Mac, but running the same code compiled for Win32 (using 
V4RB) it's slow... This has nothing to do with a slow pc, ran it on a 
top of the notch dual processor pc and it was still 5-10 times slower 
than my humble one processor G4 PowerBook.

Hope you find a fix soon, my client would be very pleased to see her 
application speed up to my demo (ran on a Mac) presentation.
