Requirements for copy and paste via HTML in View?

Hi everyone,

I'm having trouble setting up clipboard redirection in View:

I imported the Administrative Templates and set the GPOs (...\VMware Blast\Configure clipboard redirection and \Not Overridabel Administrator Settings\Configure clipboard redirection)

I can copy text (but nothing else) if I use the Horizon Client but I can't copy anything via Blast.

All I get is a window saying "Copy and Paste are unavailable"

Environment:

OS of the virtual Machine: Windows XP

OS of the machine running the webbrowser: Windows 7

View 6.2

Same result with IE11 and FireFox

Did I miss a configuration/requirement somewhere?

Thanks!

Frank
