I'm having an issue where when I link to an email box using (<a href="mailto:firstname.lastname@example.org">image</a>) the correct email pops up BUT I also get a blank web page with "http://mktoemail.companyname.com/114COL35300048R00000000". Any ideas on how to stop the web page from loading?
that may be due to the mkto tracking link. Remove tracking on that with the mktoNoTrk class. Do a search.
