Dear Jack,
Thank you for using RSS-To-Speech gadget!
We really appreciate your ideas for the future versions and will
improve the gadget in this way.
Now it is possible to use/launch RSS To Speech Google Desktop gadget
in silent mode by setting zero volume in gadget settings (it will be
remembered at the next start). We plan to improve RSS To Speech Vista
Sidebar gadget in this way also. Both gadgets have the same
registration key, BTW.
Sorry for the late response - we had vacations, but now we are at your
service.
Thanks!
