When i set email account to IMAP instead od POP I get troubles:
1) sometimes new e-mails are not showed
2) sometimes e-mail are shown but if I click on them to open the preview, in the preview another email appears.
3) If I put back the pop server it works but leave me emails which don't exist anymore if I syncronize with the server and I cann't remove them (it freezes the screen).
Is that a cache problem?

Thank you in advance for any help.
