I have a number of issues at this time:
1- Some incoming emails are received in Gmail at one time and arrive is EmClient an hour or so later.
2- On start up, I get the message "Synchronization of folder (email address listed). Failed to upload contact (contact is listed). If I accept one of the choices in the message, it goes on to another contact with the same message.
3- When I am loading an email address in an email by name, it sometimes takes 10 or 15 seconds for the choice of names to pupulate.
The program never did any of the above when I first started using but it does all of the above all the time now.
