I have a grid(in a form) that contains a dbf file that containing some Chinese characters in some fields. When I run the form, whenever I move the cursor into those field, it changes the inputting format from English to Chinese automatically. When I move the cursor to a number field, the format become English again. How to switch off this automatical changing way? I have tried to click off the 4 boxes below in the Option menu's Field Mapping such as "Copy field format" , etc. but it still does not work.
