If the anonymous tracking is set, than the statistics for clicks are wrong.
I've tested with both setting, anonymous on and off.
If anonymous off, than i see correctly the number of clicks from the newsletter.
If anonymous on , than it seems that just one person clicked the link, but not.
On the click statistics it is to see the real number
just on the main page no.
Who has an explanation for this behavior or it is an Acymailing BUG?
