[oXygen-user] Major issue with this app and multi stand-alone windows

I have been struggling with this for years. When you drag any document into a new window, dialogs and menu options are no longer available. For example, if I drag an Xml document from the main Oxygen window into a new standalone window and then try to use the menu option: DOCUMENT | SCHEMA | GENERATE/CONVERT SCHEMA; is not available. Also, things like the Outline view, the Quick Search, Transformation Scenarios, etc.. all of a sudden are not available for any document that is hosted in a standalone window. It becomes very difficult (to impossible) to use the app when you spread windows across your desktops. Is this a known issue and can this be fixed? I'm a Windows user. Karl Stubsjoen (602) 845-0006
