Notice
1. The task manager key combination CTRL-ALT-DEL only works in the
standard desktop. In dynamic desktops, the task manager can only be
called directly from the taskbar.
2. When a dynamic desktop is closed, the application that is started
automatically by inclusion in HMIDESK.INI is closed with the desktop.
Manually started applications continue to run, however.
The applications can no longer be used, however, since they are not
displayed in other desktops. If the dynamic desktop is started again later,
applications that are still running are visible again and can continue to be
used.
3.
All external applications (e.g., ProTool, Transline) that use the basic
HMI Advanced system must be started on the HMI desktop if they are to
be executed in parallel with HMI Advanced.
Background: The master control subsystems cannot be used beyond
desktop limits because Windows restricts window communications to
one desktop.
4.
16-bit applications are always started by Windows XP in the login
desktop and so do not work in a dynamic HMI desktop. The desktop
switcher can therefore not be used if 16-bit applications are being used in
HMI Advanced. In this case, HMI Advanced must be started in the
conventional way.
