Generically speaking, font metrics are different between different versions of windows as far as running FPW on them is concerned. IOW running an FPW 2.6 app designed for WIN 3.1 in WIN 95 will often display screens and objects with slightly different sizes. Hence the position error. I have seen this in my own FPW 2.6 apps runing in WIN 95. The only solution I know is to find the code causing the position error and resize the control or the main screen.
