Horizon Blast - Disable Users Access to Ctrl-Alt-Del

Hi,

With the Horizon Blast(HTML5) client, the user has the option of selecting Ctrl-Alt-Del from the 'menu' bar.

Is it possible to disable/remove this option somewhere in a .properties file on the Horizon View server ?

My use case applies specifically to hosted apps, and I appreciate this is achievable with Group Policy, but I wanted to check if I could disable at the client end.

Thanks for your help,

Richard.
