Ok. On a standard VFP form, I've got a web browser control. I do nothing with the browser (ie I don't display anything in it). In the form's activate event, I've put ON KEY LABEL F5 wait window 'F5'. When the form is run and I press the F5 key, no wait window appears. If I remove the browser control and run the form then press the F5 key, a wait window appears.
