third or fourth edit: ok, pictures fixed. They're really big, but this bbcode version doesn't seem to accept scaling information in the img tag, and my Firefox seems to be displaying them way larger than they actually are (2560x1600). So I'd suggest saving them locally and looking at them -- they're a pain in the forum. Sorry!
I'm seeing different behavior on Vista with 15 and 16 than I did with 14 for windowed zooming; it doesn't work very well for me anymore.
I have a giant monitor, 30", running at 2560x1600. In release 14, I would run in windowed mode, simply scroll the standard DF screen at the beginning to near full-size, and then back it off a bit. This is kind of like running fullscreen, in that the letters are very large, but I get the full widescreen, and I can back off the zoom when I need to see more stuff.
In 15 and 16, I don't seem to be able to zoom UP, only DOWN. It scrolls larger like maybe one click, and then starts moving the image progressively toward the center of the screen without changing the size further. When I'm running DF itself, full zoom out looks like it did on 14, and then as I zoom in it looks normal until, I think, it hits the point that it would start to magnify letters. At that point, the screen steadily shrinks, as it realizes that it doesn't have as much room to display data anymore. The actual letters don't get bigger, the game just THINKS they get bigger, so I end up with a tiny viewport in the center of my screen, surrounded by blackness.
Here's an image of what it should look like, and how .14 works:
Here's an image of what it looks like, fully zoomed in, with 15 or 16:
Aha! I thought. Maybe I should just be using that other type of scrolling he keeps referring to. So I tried hitting control-F10 and zooming all the way in, and voila:
Help?
