[TYPO3-english] excludeAlreadyDisplayedNews

[pit]

hi i have a problem with tt_news and "excludeAlreadyDisplayedNews=1"
on first load of the page (after clearing the cache in BE) it works fine.
a reload of the webpage (ctrl f5 or by clicking home button 
"index.php?id=1") it will show duplicate entrys from tt_news.

disable cache in setup "no_cache=1" it works always...

it is a very large site so disabling the cache is not the solution.

some suggestion on this issue?


tt_news 2.5.2 same in 2.6.0
TYPO3 4.2.6
