Re: XP x 3+clipper=SLOW

i had a similar problem.

they were causeb by the "commit" command.

no problems working local on w95-winMe, no problems on most
win XP systems working local or on networkdrives, but in some
contsellations the problem occured.

removed the "commit" command from the do....while-loop and placed it
behind the loop....
