One for the tech heads...

I tried to open a DAT file using Notepad (I know... not very clever..) then removed any association using Windows Explorer/tools/folder options/ file type to remove the association, which worked fine.

Now if I open a DAT file and select the only "open" option and then selecting the "select the program from a list" and enter.. I get TWO Notepad icons in a "recommended List" .... how do I remove them???

I await inspiration
