Works for me here with Win7 Home Prem x64, so the problem would seem to be specific to your system. I would first check for any malware that might be somehow interfering with things.
I have a few gadgets I liked in Vista like weather and regional clocks. However, I have discovered that any gadget with settings to be applied can't have settings changed in my Windows 7 Home Premium 64. I have tried many. Is there a fix for this?
