No problem! My recollection is a bit hazy, and I'm not active enough in retrocomputing to refresh it. I was aware that applications could use their own graphics modes, but I wasn't aware anymore just how often "productivity" software did that too. But of course, it made sense, since the Workbench screen was limited to 4 colors (in order to save memory, I guess, especially the precious "chip memory" that was accessible to the custom chips), and on their own screen they could use a whopping 16 colors :)
