>When one of my VFP forms is running, there are a number of toolbars open with command buttons in them. The command buttons are larger than small toolbar button size because the application sports a touchscreen user interface. The problem is that the buttons occasionally disappear! If the area where the button should be located is clicked, the button appears. However, the other buttons in the toolbar do not. Sometimes, all the buttons in a toolbar or several toolbars will appear after an event fires. The event can be one of the form or form control events. Any idea what’s going on here?


It's called 'coordination'. I believe the VFP sample TasTrade has an example of how to coordinate Menus, Toolbars & Forms.
