Hi Mark,

>I get this message "This program has performed an illegal operation", I close the error and get "PAVISUAL caused an exception 10H in module VFP500.DLL at 015f:100685e4". PAVISUAL is the name of my application. Does anyone have some feedback as to what is causing this error. It is not a consistant error. Thanks

A common cause for a GPF is a dangling reference. Make sure you set all object references to NULL, before you release an object.
