Thanks, Bulkhead. I was so annoyed with this I deleted the program from my Windows machine. Then I cleaned the registry and of course expected this issue would disappear. Wrong. It kept happening. Worse, I discovered I have zero access to customer support unless I upgrade to the paid version. I followed your advice, and also deleted two cookies attached to evernote.
Evernote's corporate philosophy of intrusiveness is insidious. The program is is now gone from my computer, never to be seen again. I have no respect for a company like this.
