Yesterday I downloaded the web appbuilder dev ed. While trying to mess around with adding widgets, I discovered that some widgets will not let me click "okay" to add. This happens with custom widgets and default ESRI widgets. Some have let me add them at one time, but not allowed me to add them later. Some have not allowed me to click "okay" to remove them after I add them. Some of them will allow me to add them to one location in the app but not another location. For example, sometimes I have been able to add the About widget in my test app, but sometimes I have not been able to add it. I am able to click "okay" to get to the widget configuration window, but only able to click "cancel" in that window. Has anyone else had this issue? Any suggestions on how to fix it?
