Vista's 'Ease of Access' offers an option to change the size of text and icons - e.g.
Adjust Font Size (DPI)
This link opens DPI Scaling (DPI = dots per inch), which also relates to pixel size.
I'm not sure if this is the same as changing font size under xp, but it has the undesirable effect of screwing up custom draw buttons.
Does anyone know of a way to determine when this option is 'on' so I can adjust accordingly?
cheers
