A recent (September 2009) purchase of a 17" laptop with a high resolution (1920x1200) screen uncovered problems introduced by screen scaling which I had not previously considered. Vista and XP have a user option to adjust the assumed dots per inch (DPI) screen resolution. Without other knowledge, the system assumes 96 DPI. If you use a screen with higher resolution, text and other graphics elements will display with 96 DPI scaling and show smaller than expected. In my case, too small for easy reading with these old eyes. My laptop screen is about 14.5" x 9" which works out to 132 DPI. I set the new resolution to 150% which is about 144 DPI which is very readable and still leaves more screen real estate than on my "old" 13" laptop. Now to the part that affects Delphi and many other 3rd party apps when screen image elements increase by 150% over their designed sizes.
I have converted a couple of programs (Brute Force and WordStuff 2 so far) and don't plan on any massive conversion effort to handle DPI scaling. Changes will be incorporated as other updates are posted. If you use DPI scaling and run across a DFF program that needs fixing, let me know.
