FMod - Struggling with the tour

Today I wrote a barebones watchdog render plane that allows the user to proceed to the next step in the tour after the viewport has been moved around a bit. That part works great, but while testing it, I discovered a problem caused by the presence of the tour panel (probably the "exit tour" link specifically): keystroke events are no longer delivered to the form. I remember going through similar issues back when I added the zoom slider, but the previous solutions do not appear to do anything here. I'm sure it's surmountable, but for the moment it's putting a damper on the whole tour thing.
