Small, annoying issue

I'm in Win 7 using OE10. My websites have suddenly started prompting me to accept cookies every time I open them. Even though I accept, I'm still prompted minutes later if I re-open the page. This is happening everywhere, on all sites that use cookies. Where is the setting in IE to globally accept them once and for all? I'm sure I've seen it somewhere........

I mean IE10.

Linky, though you should practice some control over what cookies are allowed on your machine.
