Oh I forgot to reply to the original post.
You have good reason to be concerned about ActiveX.
An ActiveX control is a full and complete Windows
program which can do anything that any other program
can do. I once wrote and ActiveX control which directly
accessed the user's video card memory, analyzed and
manipulated their broswer cache, and and took control
of several menu items in the browser including File -Save
and even the print screen key.
If this toolbar is valuable enough to you that you are willing
to have Flash running all the time in order to use it, go directly
to Macromedia's site to install it rathet than clicking "OK" on
any dialog that pops up. Be forewarned though that the programming
of the Flash viewer has been roundly criticized. One common problem
is that Flash doesn't limit CPU usage or frame speeds, so a common
animation technique used in Flash presentations will use up 100%
of your CPU, bringing your machine almost to a halt.
