Hi. I´ve just upgraded the Application Server at in a customers environment to 5.1. They are running an application with a menu system. When the user drags the menu and place it to the right on the screen, similiar to moving the task bar to the right or left side instead of the bottom. We are recieving the following error. "Windows error when updating the window" This worked in version 4.2 of Application Server client. Is there any solution to this? Regards Johan
