I have a form on infopath that when tabbing through, tends to go off into sections outside the form, where there is no data. It also will not tab into controls, such as radio buttons and drop-down menus. Has anyone had this problem? The tabbing order has all been set to 0, so I am not sure what is causing this issue.
Setting the tab order to 0 on all items is what is probably causing the issue. Without that set, there is no direction to specify which field to goto next. If you want a control skipped in the tab index, you can use -1. See http://office.microsoft.com/en-us/infopath-help/change-the-default-tab-order-for-controls-HP001098468.aspx for more details on tab ordering.
