This is a FAQ for when Balsa appears to lock up, or other things that you think should be happening aren't. If you can't figure out how to do something but Balsa lets you do it, that's a bug. Report it.
Odds are it isn't. Watch out for:
If you don't have threading, Balsa will stop responding when it sends and receives email. Use threading, if possible.
Balsa is opening or closing a large mailbox. This could take a while, especially when this file is accessed via NFS.
A dialog box is being displayed but it is obscured by another one. This seems to happen under Sawfish. Try moving the windows around and see if there's a hidden dialog somewhere.
Your print command is probably wrong. It defaults to "a2ps -d -q %s". Use the configuration window to change it to something that works.
There are some problems with libmutt and deleting messages. We believe them to be solved now, but they may be lingering. Known causes of messages seeming to be deleted but not really are:
Mail arrives in the folder before the deletion is committed. This is believed to be solved.
Many messages were deleted and the folder was closed and reopened quickly. This is also believed to be solved.
Were you checking your mail? Probably. This is the window that displays progress for retrieving POP3 mail. If you don't have any POP3 accounts, it will still appear -- but it'll disappear almost instantly.
