>>Remarks:
>>The AutoYield property should be set to false (.F.) when a form contains an ActiveX control. Setting AutoYield to false (.F.) prevents events for an ActiveX control from executing between lines of user program code. For example, if AutoYield is set to true (.T.), clicking an ActiveX control while user program code is executing may cause an event for the ActiveX control to execute, ignoring the user program code for the event, producing undesirable or unpredictable results.

Most of the time you don't need to worry about it. You can leave it default. In cases where it seems an Autoyield issue, it is almost always something else.
