>In a certain function, I am relying on property Application.ActiveForm. It used to work, but "suddenly" (may have been weeks ago, I don't know) it stopped working - the debugger tells me, can't evaluate expression Application.ActiveForm. _vfp.ActiveForm doesn't work either. And yes, a form is indeed open at that moment. What can be the reason for VFP not being able to process Application.ActiveForm? And is there any similar property, safer to use?

You can try _Screen.ActiveForm.

Did you by chance add an ActiveX control to the form? FYI, ActiveForm could be a reference to it and not the form.
