The pull down menu for changing the Type of caption from "Pop-On" to "Paint-On" doesn't work. Sometimes I can see a flicker of the menu, but it dissappears immediately. Pop-On is the default and that is all that can be selected.
what happens is it works when first opened, but then glitches out. the stream doesn't matter, once it glitches it happens on all of them. The fix is to quit the application and reboot, or use the scroll wheel on my mouse to select the correct menu.
