Yes, VFP has a problem with Dual Interface controls and improperly picks the wrong one
to work with <s>. The result is that any control that doesn't send it's interface definition
in just the right way will crash VFP.

To fix use SYS(2333) in the command window which forces controls to use the IDispatch
interfaces that VFP supports.

Same goes for the Internet Explorer Web browser control and any of the new 'light weight'
ActiveX controls.
