Jerry,
In addition to AutoYield you may also want to set SYS(2333,0), which disables dual interface support. I may be wrong, but I don't think other systems support dual interface so most ActiveX controls probably don't either unless they were written with VFP in mind.
Highly doubtful. Below is straight out of help:
The ActiveX control dual interface (VTABLE binding) is an optimization supported by Visual FoxPro. If an ActiveX control doesn't use the dual interface, you can disable the optimization while using that control. If an ActiveX control does not perform properly when the control is instantiated, issue SYS(2333) or SYS(2333, 0) before the control is instantiated to disable dual interface support for the control. After the control has been instantiated, issue SYS(2333, 1) to enable ActiveX dual interface support for any controls that are later instantiated.
