Hi Everyone.
I have a problem with the sidebar on Vista HP. New Gadgets wont install. The sidebar loads properly and the gadgets that are there already work fine. If I go to vista gallery to download new ones they download ok I click open then run, the sidebar comes to the front and blinks but nothing installs There is nothing in the sidebar and nothing in the gallery and nothing new in the gadgets folder in either C:\program files etc or C:\users etc. I have tried lots of different gadgets from the vista gallery and none of them install.
I tried.
Downloading and installing from ie8b2
saving the downloads to my docs and installing from there right clicking and unblocking the gadget
changing language settings from english uk to english us
dragging and dropping
uninstalling ie8b2 doing the same from ie7
Coming off line stopping all running programms and installing.

doing the same from firefox 3
coming off line and stopping all running programs.
I am currently using comodo firewall and avast AV, but have tried lots of different security programs over the months . thinking that perhaps they have done something.
Any one got any ideas. Thanks in advance for your help.
