Thank you Jim (RND) for the message!
Dear JimDirt I am not sure for which gadget you are talking about, but doesn't matter, try to put the gadget inside a folder and then put the folder on the top level of your Hard disk C. All weather gadgets are creating a "weather.ini" file that it is needed to remember your preferences, don't delete this file.
Let me know if this solved your problem
I did a search for Double Weather Calender Gadget and came up with 0 results
I did a "Search" for any file with your name adni18 and came up with 4 results , and none of them were a "ini" file
ADNI18 LIVE WEATHER III.EXE C:\Windows\Prefetch 40kb PF file
adni18 Live Weather III.exe C:\Documents and Settings \Local Settings\Temp 650kb Application
adni18 Double Weather Calender Gadget C:\Documents and Settings\Start Menu\Programs\Start Up 2kb Shortcut
adni18 Double Weather Calender Gadget\Local Setting\Application Data\Stardock\DesktopX\Gadget Cache File Folder
The bottom one is a folder , but I could not find a ini file in any of it
