Hi there, thanks for the reply
I tried doing what you suggested but it didn't change anything, i have UAC disabled. The widgets i've tried are the ones that came with DesktopX (Silica To Do List, Silica Search, Silica Dictionary Search, etc) and every other widget i've tried from the gallery that has any kind of input box doesn't work. When i click the input box there is no curser and if i try to type i get the 'ping' error sound. As i said it's happening on both my Vista pc's (they are identical though) but not my XP laptop. Weird!
Widgets without an input box work fine though - Could it be possible that my firewall or AntiVirus or some other windows security thing are blocking them somehow?
