Drilllthough sometimes does not pass filter

This one is hard to reproduce, but I have often seen that one row will go to the drill through page and not pass the filter.  I beleive this happens when a drillthrough has been used in the desktop edition, and published to the web with that filter in place and not (all).   Most of the rows work fine, but the occasional row will not connect and goes back to the one last used in desktop.   The fix is to go to desktop when this is discovered, erase the drillthrough filter, and republish.  Its very hard to avoid however as these are often used during testing.

As a fix, I would suggest resetting all Drillthrough filters to (All) at publishing or saving.  There really is no point in them retaining the setting beyond the actual use.
