Q171047 Q186834FoxPro for windows fast CPU fixes are available on our website
http://www.abri.com/ foxpro page - both the list box problem workaround and recent Andrew Forber's Divide by zero problem patch.
Also if you can't find the message Paul mentioned from Andrew Forber let me know I have a copy of another posting of it. I have no idea if it works but it does physically patch the ESL file to solve the problem.
>Is there a fix (patch) available for FPW2.6 apps on fast pentium machines?
