Using the "Hello Scan" app from the help file on an ES400:
1. The quit button does not display.
2. You cannot kill the Rho app from Task Manager.
If you comment out the meta tag for the scanner, then you can kill the Rho app from Task Manager.
Thanks for that, looks like a rogue space has entered the help file... the line should actually read:
<meta http-equiv="quitbutton" content="visibility: visible;" />
I'll get the help file updated.
