Hello,
The # anchors are used in EPESI to access history of EPESI pages visited by the user. As far as I know, there's no way to mark particular link to be skipped by the history keeper.
There is another thing you can do here, is to use the JS equivalent of # anchor jump:[code]<a href="javascript:void(0);" onclick="window.location.hash='yes'">YES</a>{/code]
This should give you desired result.
Hope this helps.
Kind regards,
Arek
