The ltaskbar.exe module is used to display the list of applications running in the bottom area of the page :
If you publish a single application,
if the applications are executed one after the other via the Floating panel,
you can probably disable the display of applications in taskbar.
If it suits you, it will be enough to edit the file: tsplus\userdesktop\themes\Seamless\desktop0.ini
and search the area : [Taskbar]
In this area, search for the variable
visible = 1
And replace the value with
visible = 0
Access the properties of the desktop0.ini file and check the 'read only' attribute.
All new sessions will no longer use ltaskbar.exe.
