I am facing one issue when i call a form from another form. When i call a form using OPEN_FORM('called_form_name',ACTIVATE,NO_SESSION,l_paramlist); the menu in the application hides for few seconds and then it appears and in called form if i confirm the order a alert message will display and the menu hides once again. It will appear when i acknowledge the alert.
What Java Runtime Environment (JRE) do you have installed and are you using the 64 or 32 bit version of Windows and JRE? Typically, issues with presentation on the client side or JRE related. Installing the latest 1.6.0 JRE will typically fix the issue.
