[binc] opera client + locked folder

Hi, I'm unfamiliar with the protocol of this mail list, so if I violate anything or this is the wrong place for this, I apologize in advance.

I've got two issues.  I wanted to get mail off my limping redhat 8.0 server onto my freebsd server.  So I installed Bincimap and I used thunderbird to copy from one to the other (the linux imap was a different format and I didn't feel like trying to convert it).  This worked great until I tried copying a directory with 1800+ files in it.  All of the messages seemed to have copied, I have 1834 files in 'myfolder/cur' directory, but thunderbird won't show anything in the directory.  Additionally, I have a zero byte called "bincimap-scan-lock" in the "myfolder" directory.  if I delete it, it comes back.

Is this a problem with the client?

Here's part 2: I have been using Opera M2 mail client for the linux IMAP server.  It works great.  No matter what I try, I can not get it to view the folders.  It will connect and authenticate, but no folders show.

I went to life with bincimap, but the wiki for opera is blank.

Any idea why thunderbird works and opera doesn't?  I've seen archived mail lists where opera was used, so I assume opera and bincimap are compatible -- possibly a problem with "Path to IMAP root folder" option?

Thanks,
John
