Cache bug using max-age without a Date header

I'm having a problem I think I've traced down to a caching behavior problem
within IE.

If a 1.1 response (images) contains a Cache-Control header with a max-age
value but does not contain a Date field the max-age value is respected
initially however after the initial value of max-age expires subsequent
retrivals are never cached. The only way I've found to reset the caching
behavior until max-age has passed is to go into my internet options and
select delete files.

Are you sure that that is the only factor in your example?
E.g. the vary: header is also known to result in non-caching too.

Do you have an example somebody could watch?
