unmovable or resizable object
I've been using a filemaker template since the early 90's but because of the high resolution on my new computer the layout is too small. I'm trying to resize everything in the layout but there is a bar at the bottom of the layout that I can't change. It borders the bottom and only seems to allow me to make it wider but I can't make expand the layout downward. I'm not sure if this black rectangle is the culprit or some feature of the layout but I've searched for size limits for the layout but couldn't see anything like that. As you can see in the screenshot, I've been able to enlarge the yellow and black rectangles horizontally, but not vertically. I'm not sure what the grey box is in the background or what purpose that serves. Thanks for any help you can offer.
By the way, since I bought the new computer I've been using alt-V-I twice whenever I start up Filemaker but I'd rather permanently increase the size of the layout to avoid zooming each time I open the file.
