Any update on this?

I am not able to reproduce the problem. I haven't heard of any other customer with the problem. Here's my LastErrorText using GMail:

If you wish, please send me the account credentials for a test email account (to support@chilkatsoft.com) and I'll quickly run the test to see if I get the same error.

Thanks. I used your test email account, but found no problem. Here's my LastErrorText for Connect, Login, and SelectMailbox:

Hello! I have had the same problem after selecting mailbox. I check all mailboxes in my email account one after another and execute next code by timer (for example every 5 minutes):

if (!CheckConnection())
return;

foreach (string mailbox in GetAllMailboxes())
{   
if (Imap.SelectMailBox(mailbox))
    GetMessagesFromMailbox(mailbox);
}

Sometimes, Imap.SelectMailBox("mailbox") returns false and all next calls of the Imap.SelectMailBox("mailbox") return false. What should I do in this case and how can I recognize this situation? (I use chilkat 9.5.0 for .Net 4.0) Should I close each mailbox after using?
