I don't see any electrum.dat files, just electrum files. i deleted everything and the shadow window still comes up. Somehow, it remembers my wallet transaction details??? I thought I deleted everything...
If it still remembers your details, it means the electrum.dat file is still there. It's the only place any electrum data gets stored.
Make sure you enable the "hidden files and folders" checkbox when searching.
Sorry for the slow replies, I'm travelling and can't go online very often.
