Ken, I agree with most of what you've mentioned here when it comes to touchscreen input and VFP.

Do you realize that the "Native Options buttons" can be changed to be "Graphical" and when styled this way, you can make them as large as you wish to accommodate those fat fingers?

Any serious data entry requires a real keyboard (hardware). For simple input on a touchscreen, you can use the one that comes with Windows (osk.exe) or make your own. I did the latter since osk.exe was overkill for what I needed.

My 2cents (BTW, I typed this using osk.exe. What a pain! :)

>Native combo's are a problem because they do not "size" very well. Touch screens need large controls. You can make the combo font large but the dropdown arrow remains pretty narrow. Native Option buttons are even worse. We have written our own so they can have a decent size needed for fat fingers on a touch screen.
