Problem with RubyWebDialogs and Ruby 1.8.4

Hi,

I try to use RubyWebDialogs 0.2.0 (which seems really great) under
Windows XP SP2. But when I try run an example script, I get this error:

Insecure operation - system (SecurityError)

On the web site, it is on the “Know issues”.

Does anyone solved that problem?

Thanks
