Sidebar weather not updating
By clicking on an element you make it the current clipboard.
This way you can select older clipboards and paste them into other applications. The options of Clipboarder allow many possibilities.
Here you can, for example, click on the first checkbox to make the sidebar always visible. A disadvantage is though, that the close button of maximized windows isn't on the top-right corner anymore.
To fix this you can put the sidebar on the left side.
I’ve tested this gadget (should be available also in English).
Some other solutions could be (I haven’t tested it): 7 sidebar, 8Gadget Pack.
For example you can add a preview of the application to the sidebar.
The options of the last gadget, the weather gadget, allow you to change the city. If you don't like the sidebar you can close it there. Click on options to change the behaviour of the sidebar.So my recommendations: Don’t waste your time fixing Microsoft’s weather gadget and use a third party solution.
