Question: Objects drawn on my application page seem to disappear, and other objects cannot be selected. Why is my VTS application behaving strangely?
A: It could be that your application's .RUN files have not been updated with your application's .SRC files. The application needs to be compiled. Stop the application, then recompile and run the application. When you place the application in design mode (i.e. open the Configuration Toolbox), any objects you draw on your pages will behave as they should, and you will have the ability to select them.
Information on compiling an application can be found in Compiling an Application.
