If you want to deactivate the Auto-Update-Function (which actually doesn't seem to work anymore, since the website [link] is down), go to C:\Users\"your username"\AppData\Local\Microsoft\Windows Sidebar\Gadgets\DesktopClock.gadget\JS and edit the "gadget.js" file. (You should first make a copy of it for backup purposes).
How to edit? Open the file with notepad, then type "//" at the beginning of each line associated with the update function, just like this:
Thanks for the info, I just downloaded your update from here [link] and it works great and I didn't have to edit the js file at all. Maybe you should just replace the link for the main download with this one . Thanks so much.
Suddenly the gadget told the update is available. So by clicking the link in the preferense, I downloded the new one, but it still says update available! By checking the contents og the gadget, the installed version is 188.8.131.52.
