E-mails stop arriving, sometimes for months, things load up on computer, watching some things difficult as it can slow down or stop/start. E-mail from a survey company I do not use that often has just popped up onto my e-mails (since I do not use all survey sites most of the time it is easy for one I do not use very often to stop e-mails from arriving in my inbox for months at a time and for me not to notice) and it could be a month or two since I last remembered it being there. Another place I subscribe to just sent me week 4 of 4 parts but did not receive e-mails for the other 3. This is fairly typical with the e-mails as this has been happening for about 2 years. Computer got a clean bill of health whilst the e-mails were being stopped from arriving in my inbox. Companies in the past have said their e-mails were being sent back. Deleted all e-mails from one company and have had none sent since.
