To Alex: The forum glitches?

I tried to post a reply to your reply to the thread with subject "Blank dates come up as #ERR ??", but found that it didn't register as seen from here: http://www.activewidgets.com/messages/. I tried it again and again (4 times in all) to no avail, however when I look at the same thread from here:http://www.activewidgets.com/grid.howto.fix/sort-empty-cells.html, all my replies were there.
In fact, I just noticed that http://www.activewidgets.com/messages/ did finally update as well... Strange...

Sorry, for that. I made something wrong with cache-control headers, so please use 'refresh' button if you don't see updates. I'll try to fix this asap.
